Hello thanks again. I gotten your advice previously and wanted to check to see if I did this problem correctly. Is this answer 1458 ft or the reverse of 189 ft?
If the measures of two corresponding sides of two similiar solids are 3 meters and 5 meters, what is the ratio of the surface areas of the solids?
Your answer is wrong. They don't ask for a length; they ask for a ratio.
The answer is (5/3)^2 = 25/9
