Question

The dimensions of a metallic cuboid are 100cm×80cm×64cm.It is melted and recast into a cube. Find the length of each edge of cube.
​

Answer 1

The dimensions of  a cuboid are given to be 100cm × 80cm × 64cm

Now, it is recast into a cube

We have to find the length of the side of the cube

So, the volume of the cuboid will be equal to the volume of the cube

volume of cube = volume of cuboid

               (side)³ = 100 × 80 × 64

               (side)³ = 512000

                   side = ∛512000

                           = 80 cm

Hence, the side of the cube formed will be 80 cm
