Question

Which of the following are perfect cubes?
(a) 2,190​

Answer 1

Answer:

The numbers such as 1, 8, 27, 64, etc. are known as perfect cubes or cube numbers. When a cube is broken or cut, total volume still remains the same. Hence we can observe that to construct a cube of edge length '2a' with cubes of edge length 'a' we need to have 8 cubes of edge length a.

Answer 2

Square root of 2190 cannot be reduced, reduced because it already is in its simplest form
