The surface area of a rectangle prism is 166 square feet. The surface area of a similar rectangular prism is 1494 square feet. If the length of the smaller prism is 5 feet, what is the length of the larger prism?
The ratio surface area of two similar rectangular prism has the relationship of square time of the ratio of length. So the 1494/166=9=3². So the length of two has ratio of 3. So the length of the larger one is 5*3=15 feet.
