10.2.1 Surface Area of Prisms and Cylinders − Practice
1. Find the lateral area and the surface area of a right rectangular prism with an 8 cm by 9 cm base and a height of 13 cm.
2. A regular pentagonal prism has a height of 12 in. and base edge length of 8 in. Find its lateral area and surface area.
3. A right cylinder has a base area of 81 π cm 2 . Its height is 2 times the radius. Find the lateral area and the surface area of the cylinder.
4. A right cylinder has a circumference of 14 π cm. Its height is 3 times the radius. Find the lateral area and the surface area of the cylinder.
5. A right rectangular prism has length 9 cm, width 5 cm, and height 3 cm. If the length, width, and height are doubled, what happens to the surface area ?
6. A right cylinder has radius 9 cm and height 12 cm. If the radius and height are tripled, what happens to the surface area?
