Question

The side of a cube is 5 cm. Find the volume of the cube.

Answer 1

Hint: A cube is a three-dimensional figure with all the edges equal in length. It has a total of 6 faces, 8 vertices and 12 edges. Each face is a square.

Complete step-by-step answer:
 The figure of cube is given below-

We have to find the volume of the cube. The volume of the cube is given by the cube of its edge.
$\mathrm V=\mathrm{side}\times\mathrm{side}\times\mathrm{side}=\left(\mathrm{side}\right)^3$
The length of the side is 5 cm.
So, the volume will be-
$\mathrm V=5\times5\times5=125\;\mathrm{cm}^3$
Hence the volume of the cube is 125 ${cm}^{3}$.

Note: One common mistake in such questions is that students forget to write the units, or write the units which are the same as the length. Instead, when we multiply the length three times, the units will also have a cube sign as shown in the answer. Similarly, when finding the area the units become ${cm}^{2}$.
