Solution

Volume of the metallic cuboid
=100 × 40 × 54 cm3
=216000 cm3
Since the metallic cuboid is melted and is recast into a cube, the volume of the metallic = volume of the cube. Let the length of each edge of the recast cube be a cm, then,
Volume of the cube = Volume of the cuboid
a3=216000
a3=63×103
a=6×10=60cm
