A rectangular prism has a volume of 960cm. It's width, length, and height are in the ratio 3:5:8.
A) Determine the dimensions of the prism
B) What is the ratio of the left side to the front to the top of the prism by surface area?
C) Calculate the surface area of the prism.

3x*5x*8x=960
x^3=960/120
x= cubrt(8)=2
sides then are 6;10;16 
how do i solve B) though?
