The cube of a number can be a positive or negative number. The cube of odd numbers is always an odd number and for even numbers, the cube is even. The formula to find the cube of a number is, \( n^3~=~n~\times~n~\times~n \), where n can be any number. For example, ...
What is the Cube Root Formula for Negative Numbers? Yes, it is possible to find the cube root of negative numbers. For example, -64 = (-4) × (-4) × (-4). We can write -64 as the product of 3 negative 4's. Thus, ∛-64 = -4 because the product of three negative values...
So mathematically, the following is the perfect cube formula: A number NN is a perfect cube if we can write it as: N=a∗a∗aN=a∗a∗a, where aa is an integer. Generally, if we can find what the cube root of a number is, and if that is an integer, our number will be...

12. It is of great significance to find reliable methods for the removal of a large variety of environmental pollutions in surface water taking advantage of the natural energy source available, solar light13. Semiconductor photocatalysis (such as BiOBr, TiO2, WO3, SrTiO3, Ag2MoO4and ZnO) is ...
Numbers (150, 100, 80) indicate the specimen’s diameter in millimeters (mm). Slender 1 indicates samples with slenderness ratio equal to 1 [11]. The amount of cement added to CSRE will impact its mechanical strength and durability, especially in regions with many days per year where ...
