Question

If an edge of a cube is of length 15cm. Then find its volume.​

Answer 1

Answer

• Volume of cube = 3375 cm³

Given

• Length of edge of a cube = 15 cm.

To Find

• The volume of the cube.

Step By Step Explanation

Given that the length of edge of a cube = 15cm.

We need to find the volume.

$\red\maltese{\boxed{\bf{Volume_{(Cube)} = {Edge}^{3}}}}$

By substituting the value

$: \implies\sf \:Volume = {(15 \: cm)}^{3} \\ \\ : \implies \sf \: Volume = 3375 {cm}^{3}$

Therefore volume of cube = 3375 cm³

☆Extra Formulae

For a cube having each edge = a units, we have -

• Volume = a³ cubic units.

• Total surface area = 6a² sq. units.

• Lateral surface area = 4a² sq. units.

• Diagonal = √3a units.
