The formula a=6s^2 will calculate the surface area of a cube. suppose you have a cube that has a surface area of 216 square inches. what is the length of each side?

216 = 6s^2

can be solved in the following manner.

216/6=s^2
36 = s^2
sqrt(36) = s

flip for better overview

s = 6

the length of each side is 6 inches. :)

Answer: c. x y2 04 66 16

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
