The surface area of a triangular prism is 18.5 square inches. What is the surface area of a similar solid that has been enlarged by a scale factor of 2.5?
Since area is in ration squared like if a 2 by 2 square had it sides lenght times 2. it would be 4 by 4. But the area would change by 2^2 which is 4. In the same principle it would 18.5*2.5^2
