Question

find the volume of a cube having length 8cm.​

Answer 1

Answer:

The volume of a cube with a side length of 8 cm is 512 $cm^3$.

Step-by-step explanation:

The volume of a cube having a side of  length $'a'$ is,

$Volume =a^3$

We have given that the cube has side length 8 cm. That is

$a=8\ cm$

The value of $a$ is 8  cm. Hence the volume is,

$Volume = 8^3=8\times 8\times 8 = 512 \ cm^3$

So the volume of a cube with a side length of 8 cm is 512 $cm^3$.

Answer 2

Answer : The Volume of Cube = 512 cm³

Step-by-step Explanation :

Given : length ( side ) of the cube = 8cm

To find : Volume of Cube = ?

So,

Volume of Cube = ( side )³

Substituting the given value in the above formula,

We get,

Volume of Cube = 8³

Volume of Cube = 512 cm³
