Question

Периметр грани куба равен 1 м. Какой длины рёбра куба?

Answer 1

1м = 100см
100:4=25 (см) - длина ребра куба

Answer 2

Perimeter of a Cube

To find the length of the cube's edge, we need to know the perimeter of one of its faces. The perimeter of a square (which is the shape of each face of a cube) is calculated by multiplying the length of one side by 4.

Let's denote the length of the cube's edge as x.

The perimeter of one face of the cube is equal to 1 meter, so we can set up the following equation:

4x = 1

To find the value of x, we divide both sides of the equation by 4:

x = 1/4

Therefore, the length of the cube's edge is 1/4 meter.

Please note that the information provided is based on the assumption that the perimeter of one face of the cube is equal to 1 meter.
