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?

OpenStudy (anonymous):

ahhh the ratio of the surface areas is equal to the respective ratio of sides squared

OpenStudy (anonymous):

uh what would that be?

OpenStudy (anonymous):

the respective ratio of the sides scared

OpenStudy (anonymous):

squared*

OpenStudy (anonymous):

well let the side you do not know be x....so 166/1494=(5/x)^2

OpenStudy (anonymous):
