I really need help Lesson 16 Review
Calculate the surface area of each pyramid with the following values. (P = perimeter, b = one side of the base, s=side, h=height). Number of sides is given in each problem. The first two have hints to let you know what the shape of the base is

1. P = 12 ft, s = 4 ft, b = 4 ft, h=2 ft, 3 sides (base is a triangle)
2. b = 4 in, P = 16 in, s = 12, 4 sides (base is a square)
3. P = 48 m, b = 12 m, s=12, 4 sides
4. P = 45 yds, b = 15 yds, s=15, h=12, 3 sides
5. b = 6 ft, P = 24 ft, s=6, 4 sides
6. P = 15 ft, b = 5 ft, s=5 ft, h= 4, 3 sides
7. b = 4 in, P = 16 in, s=11, 4 sides
8. P = 40 m, b = 10 m, s=10, 4 sides
9. P = 45 yds, b = 15 yds, s=10, h=8, 3 sides
10. b = 16 ft, P = 64 ft, s=8, 4 sides
11. b = 5 ft, P = 20 ft, s=7, 4 sides
12. P = 45 ft, b = 15 ft, s=10, h=8, 3 sides
13. b = 13 in, P = 52 in, s=11, 4 sides
14. P = 28 m, b = 7 m, s=8, 4 sides
15. P = 27 yds, b = 9 yds, s=30, h=25, 3 sides
