Question

A metallic cuboid of dimension 18m× 12 m× 8 m is metaled. Find the minimum volume of molten metal which shoula be added to mould it into a cube whose edge is ' a'cm, where 'd' is an integer.
​

Answer 1

Answer:

1. Volume of cuboid = 18x12x8 = 1728

2. So, volume of cube = Volume of cuboid = 1728

3. Since all sides of a cube are equal to find one side = cube root of 1728 = 12

4. Since the answer is zero we do not need to add any amount of molten metal to make it into a cube as it already has the perfect quantity to be moulded into a cube.
