A right rectangular prism has a width of 6.8 meters and a legnth of 28 meters. If the surface area of the prism is 2608 meters what is the height?

a. 20 m
b. 22.5 m
c. 24.5 m
d. 30 m
e. 32 m

You have to know the formula for finding the total surface area of a rectangular prism.

Surface Area = Sum of all flat areas

Note that you have six flat areas in a rectangular prism.

The sum of A_1 to A_6 give the total surface area. Can you do it now? :)
