First off, what is the formula for the volume of a cube?

I don't know

jordanloveangel · Answer

The total volume is x^3 + 1^3 = x^3 + 1 

x^3 + 1 = (x + 1)(x^2 - x + 1) 

Let x = 3 

x^3 + 1 = 3^3 + 1 = 28 

You can confirm this by using the factors. 

(3 + 1) ( 3^2 - 3 + 1) 
(4 ) (9 - 3 + 1) 
4 * 7 = 28  i think

The formula is the side length of the cube to the power of three, aka cubed. So if the side length is 1, what is the volume?
