Question

The three co - terminus edges of a rectangular solid are 36 cm, 75 cm and 80 cm respectively. Find the edge of a cube which will be of the same capacity:

Answer 1

Volume of cube = volume of cuboid

Volume of cube $=36cm\times 75cm\times 80cm=216000c{m}^3$
Volume of cube $=a^3$
So, $a^3=216000c{m}^3$
$a=60cm$
