The volume of a cube is found by using the formula l^3, where l is the side length. If the side length is 4x^3, what is the volume of the cube?
A. 64x^6
B. 12x^9
C. 4x^6
D. 64x^9
D. 64x^9 This is because 4x^3 is the side length and you substitute it into l^3 and you get (4X^3)^3 (4X^3)^3 is the same as (4X^3) x (4X^3) x (4X^3) 1. (4X^3)^3 2. (4X^3) x (4X^3) x (4X^3) 3. (16X^6) x (4X^3) (remember when multiplied, exponents get added to each other) 4. 64X^9 After multiplying all three of those you get 64X^9 D. Hope this helps
