A cube has a volume of 64 cubic inches. what is the surface area?
volume is created by multiplying length times width times height. V = LWH. Because the sides are equal, the sides equal 4 inches each. Cube root of 64 = 4x4x4x4. The area of one side of the cube is 4x4 = 16. there are 6 sides to a cube, so 16 x 6 equals 96 inches.

Denise earned the grades 89, 85, 96, and 87. What score does she need to get an average grade of 90?
90 equals 89 + 85 + 96+87+x divided by 5. Add numerators and multiply both sides by 5. 450 = 357 + x. 450 - 357 = 357-357+x. 93 = x.
