What are the formulas for the surface area and volume of cuboids and cubes?

1, the formula for calculating the surface area of a cuboid:

The surface area of a cuboid = length× width×2+width× height× 2+length× height× 2, or: the surface area of a cuboid = (length× width+width× height+length× height) × 2.

2. Calculation formula of cuboid volume:

Cuboid volume = length× width× height. Let the length, width and height of a cuboid be A, B and C respectively, then its volume: V=abc=Sh.

3. Calculation formula of cubic surface area:

Because all six faces are equal, the surface area of the cube = bottom area ×6= side length × side length ×6.

4, cube volume calculation formula:

The volume of a cube (or called the volume of a cube) = side length × side length × side length; Let the side length of the cube be a and the volume be v = a× a× a.

Extended data:

Characteristics of the cube:

1 has eight vertices, and each vertex is connected by three edges.

2. A cube has 12 sides, and each side has the same length.

A cube has six faces, and each face has the same area.

Features of a cuboid:

1 has 6 faces. The reverse sides of each group are exactly the same.

2. A cuboid has 12 sides, and four opposite sides are equal in length. According to the length, it can be divided into three groups, each group has four sides.

All formulas for cuboids and cubes?

Height, that is, V=Sh(S is the bottom area) 2. Formula of cuboid surface area: S=2(ab+bc+ca) 3. Because the cuboid I * * has six faces, ab, bc and ca respectively represent three faces with different areas, corresponding faces and so on, so it is multiplied by a 2. 4. Cube surface area formula: S=6(a? ), where a*a is the area of a face, and the area of each face of the cube is equal, so it is 6 times. 5. Cubic volume formula: V=a? 6. Because the bottom area of a cube is a*a, this formula can be evolved as: V=Sa. References:

All formulas of cuboid

The formula of cuboid cube is mainly the calculation formula of volume and surface area, as follows: 1, cuboid volume formula: v=abc (volume = length× width× height), because length× width is the bottom area of cuboid, this formula can be evolved into cuboid volume = bottom area× height, that is, V=Sh(S is the bottom area) 2, cuboid surface area formula: 4. Cube surface area formula: S=6(a? ), where a*a is the area of a face, and the area of each face of the cube is equal, so it is 6 times. 5. Cubic volume formula: V=a? 6. Because the bottom area of a cube is a*a, this formula can be evolved as: V=Sa. References:

All formulas of cuboid

They have many formulas. This is the formula of volume and area. 1. cuboid 1. Surface area Because the two opposite surfaces have the same area, count the back two surfaces first, then the front and back, and finally the left and right sides [5]. Let the length, width and height of a cuboid be a, b and c respectively, then its surface area is S = (ab+bc+ca)×2, which is also equal to 2ab+2bc+2ca, 2 (AB+BC+CA); Formula: the surface area of a cuboid = length× width×2+width× height× 2+length× height× 2, or: the surface area of a cuboid = (length× width+width× height+length× height) × 2. 2. cuboid volume = length × width × height. Let the length, width and height of a cuboid be a, b and c respectively, then its volume is. Because the cuboid is also a kind of prism, the formula for calculating the volume of prism is also applicable. Cuboid volume = base area × height, that is, (s is base area) 2. Cube 1, surface area formula Because all six faces are equal, the surface area of a cube = bottom area ×6= side length × side length ×6 2, and the volume of a cuboid (or cube volume) = side length × side length × side length; Let the side length of a cube be a, then its volume is: V=a×a×a First, take the diagonal of the upper bottom surface and calculate, and get that the diagonal of this surface and the edge it intersects are the sides perpendicular to the upper bottom surface, and the hypotenuse of this right triangle is the diagonal of the body. According to Pythagorean theorem, it is concluded that the diagonal of the object is equal to 3 times the length of the root side. Cube belongs to a kind of prism, and the volume formula of prism is also applicable (to correctly distinguish between body diagonal and face diagonal, body diagonal is a concept in plane geometry and body diagonal is a concept in solid geometry). It can also be calculated by cube volume = bottom area × height. At the same time, the body diagonal of the cube is also equal to: the square of the body diagonal = the square of the length+the square of the width+the square of the height. A cuboid has six faces. The reverse sides of each group are exactly the same. (2) A cuboid has 12 sides, and four opposite sides are equal in length. According to the length, it can be divided into three groups, each group has four sides. (3) A cuboid has eight vertices. Each vertex connects three edges. The three edges of a cuboid are called length, width and height. (4) Two adjacent sides of a cuboid are perpendicular to each other. Cube features [1] A cube has eight vertices, and each vertex connects three sides. [2] A cube has 12 sides, and each side has the same length. (3) A cube has six faces, and each face has the same area. (4) Diagonal line of cube: \sqrt{3}a Reference Baidu Encyclopedia-Cuboid Baidu Encyclopedia-Cube

Formulas for all cuboids.

The area of the top surface, bottom surface and each surface of a cuboid is equal to the length times the width. The area of each front and back is equal to the length multiplied by the height. The area of each face on the left and right sides is equal to the width times the height. Surface area of cuboid = (length x height x width x height x width x height) X2 or length x height x width x height X2 Surface area of cuboid = side length x side length x volume of cube = side length x side length x side length x side length of cuboid = sum of side lengths of cuboid =4X length x width x height or 4X (length x width x height). Sum of sides of a cube = 12X volume of long-side objects in water = total volume now-original volume volume of objects in water = height of water rising x surface area of cuboid without cover = length x width x height) X2 volume of cuboid without cover = length x width x height finding factor () X()= product of this number.

All formulas of a cuboid.

Surface area Because the two opposite surfaces are equal in area, the back two surfaces are counted first, then the front and back, and finally the left and right surfaces [5]. Let the length, width and height of a cuboid be a, b and c respectively, then its surface area is S = (ab+bc+ca)×2, which is also equal to 2ab+2bc+2ca, 2 (AB+BC+CA); Formula: the surface area of a cuboid = length× width×2+width× height× 2+length× height× 2, or: the surface area of a cuboid = (length× width+width× height+length× height) × 2. Cuboid = length× width× height. Let the length, width and height of a cuboid be a, b and c respectively, then its volume is. Because the cuboid is also a kind of prism, the formula for calculating the volume of prism is also applicable. Cuboid volume = base area × height, (s is base area). Extended data:

The feature (1) cuboid has six faces. The reverse sides of each group are exactly the same. (2) A cuboid has 12 sides, and four opposite sides are equal in length. According to the length, it can be divided into three groups, each group has four sides. (3) A cuboid has eight vertices. Each vertex connects three edges. The three edges of a cuboid are called length, width and height. (4) Two adjacent sides of a cuboid are perpendicular to each other. References:
