Question

The length, breadth and thickness of a metal cuboid are 28 cm, 14 cm and 7 cm
respectively. It is melted and made into a cube. What is the length of the edge of the cube so formed?​

Answer 1

Answer:

Volume of cuboid = volume of cube

$l \times b \times h \: = {a}^{3} \\ 28 \times 14 \times 7 = {a}^{3} \\ \\ 2744 = {a}^{3} \\ \\ a = {2744}^{ \frac{1}{3} } cm$
