Two similar rectangular prism have corresponding sides that measure 5 feet and 6 feet.
If the surface area of a smaller prism is 525 square feet, what is the surface area of a larger prism?
For similar figures, area is proprtional to the square of corresponding length dimensions, and volume is proportional to the cube.
In this case, the areas are in a ratio os (6/5)^2 = 36/25.
So the area of the larger prism is
(36/25)*525 = 756 ft^2
