Find the length of the edge of the cube if the volume of the cube is 125 cm3.

In this task, we need to find the value of the edge of the cube;

To do this, let’s remember what a cube is;

A cube is a geometric figure in which all sides (edges) are equal to each other;

From this definition, we write down the formula for the volume of a cube;

V = a3, where V is the volume of the cube, and is the side (edge) of the cube;

Since we know the volume of the cube, according to the condition of the task, then we express from this formula the value of the side (edge) of the cube “a”;

To do this, you need to take the third root from both parts of the formula;

a = 3√V;

a = 3√125;

a = 5cm.
