Surface area is proportional to the square of the ratio of the sides.
\n" ); document.write( "Thus, if one prism's sides are 3 times as long, then its surface area is 9 times greater.
\n" ); document.write( "So if the smaller prism has a surface area of 15 in^2, then the larger has a surface area of 135 in^2.
