I need help with these geometry: surface area problems.

Aim: How do we find the surface area of prisms? Main Ideas/Questions Notes Find the surface area of each rectangular prism below. Rectangular 1. Prisms (or Cubes) 9 ft 7 ft 13 ft 2. 5 cm 16 cm 10 cm SA = 21w + 21h + 2wh 3. / = length 1.5 in w = width h = height 6 in 11 inAll Other Find the surface area of each prism below. 4. Prisms 9 m 12 m 16 m 15 m 5. 3 km First, find the 10 km lateral area (area of 5 km 4.1 km non-bases), then add the area of the bases. 12 km LA = hp SA = hp + 2B 6. 18 ft 20 ft h = height between bases p = perimeter of the base 12 ft B = area of the base 15 ft 23 ftFind the surface area of each cynder below. Cylinders 9. 11 yd 26 yd 10. 9 m LA = 2arh SA = 2ar2 + 2arh 15 m r = radius h = heightDirections: Find the surface area of each figure. Round to the nearest hundredth when necessary. 1. 2. 14 mm 12 in 29 mm 8 in 17 in 3. 4. 8 ft 19 ft 3 cm 11 cm 14 ft 6 cm 12.1 ft 4.3 cm 5 ft 8 cm
