Step-by-step explanation:
The volume of a cube is Side ^3
Find the cubic root of the volume to find the side length:
Side = cubicroot(216) = 6 feet.
The area of a face of a cube is s^2
Area of a face = 6^2 = 36 square feet.
Area of 2 faces = 36 x 2 = 72 square feet
Answer: 72 square feet
Profit would be the revenue minus the cost
so R=x^3-6x^2 +x +75 - C=x^2-70x =

If you are buying 32 copies of a book and each copy costs 12.34 you should multiply $12.34 by the amount of copies being bought in this case 32 so
