Answer 2

A prism has identical top and bottom surfaces and it has lateral surface (side surface).
Total surface area = 2 * area of base + perimeter * height

Answer 3

I got 980...?

Answer 4

Bottom area = 55
Top area will be the same as the bottom. Therefore, 55
Lateral or side surface area = perimeter of base * height = 30 * 7 = 210

Total surface area = 210 + 55 + 55
