Arectangular prism has a surface area of 8 square feet. a similar rectangular prism has a surface area of 200 square feet. how many times larger are the dimensions of the larger prism?
5
10
625

The surface area of the larger prism is 200/8 = 25 times larger than the surface area of the smaller one. 

From this, we can tell that the linear dimensions of the larger one are √25 = 5 times larger.
Your answer is 5
