WebFor example, 2 3 = 8, 4 3 = 64; When odd numbers are cubed, the result will be an odd number. For example, 3 3 = 27, 5 3 = 125; Perfect cube numbers can be both positive or negative integers. For example, both 8 and - 8 are the perfect cubes of 2 and - 2 respectively. Perfect cubes can be expressed as a sum of consecutive odd numbers.
