Question

For equal cubes are joined to form a bigger block of volume $32$ cubic $cm$. Find the side of each cube.

Answer 1

Let edge of cube $=a$

so, edges of new block $=a,2a,2a$

Now, volume of new block $=\left(a\right)\left(2a\right)\left(2a\right)=32$

$\Rightarrow 4a^3=32$

$a^3=8$

$s=2cm$

so, edge of cube $2cm$

Hence, the answer is $2cm.$
