Calculate the sum of the lengths of all edges of a cube if the perimeter of its face is 8 cm.

A cube is a three-dimensional figure whose faces are squares.

Perimeter of the square:

P = 4a, where a is the length of the side of the square.

Let’s find the length of the side of the square (the edge of the cube):

8: 4 = 2 cm length of the edge of the cube.

The number of edges for a cube is 12.

Let’s find the sum of the lengths of the edges of the cube:

12 * 2 = 24 cm

Answer: 24 cm
