Question

Найдмте объём куба с ребром 4см площадь его поверхности и сумму длин рёбер

Answer 1

S=4×4=16
Так как это куб все ребра будут равны это значит что длинна ребер будет ровна 4 см

Answer 2

Calculation of the Cube's Volume, Surface Area, and Sum of Edge Lengths

To find the volume, surface area, and sum of edge lengths of a cube with a side length of 4 cm, we can use the following formulas:

1. Volume of a cube: V = s^3, where s is the length of a side. 2. Surface area of a cube: A = 6s^2, where s is the length of a side. 3. Sum of edge lengths of a cube: E = 12s, where s is the length of a side.

Let's calculate each of these values for the given cube:

1. Volume: - The volume of a cube with a side length of 4 cm is calculated as follows: V = 4^3 = 64 cubic centimeters. 2. Surface area: - The surface area of a cube with a side length of 4 cm is calculated as follows: A = 6(4^2) = 96 square centimeters. 3. Sum of edge lengths: - The sum of the edge lengths of a cube with a side length of 4 cm is calculated as follows: E = 12(4) = 48 centimeters. Therefore, for a cube with a side length of 4 cm, the volume is 64 cubic centimeters, the surface area is 96 square centimeters, and the sum of edge lengths is 48 centimeters.
