Answer:
2. Surface Area = 576m^2
3. Surface Area = 300 yd^2
Explanation:
2.
Surface Area of Prism Formula:
Triangle Formula: Area = 1/2 * Base * Height
Left Triangle: Area = 1/2 * 8m * 6m = 1/2 * 48 = 24 m^2
Right Triangle: Area = 24m^2
Rectangle Formula: Area = Length * Width
Top Rectangle: Area = 22m * 6m = 132m^2
Middle Rectangle: Area = 22m * 8m = 176m^2
Bottom Rectangle: Area = 22m * 10m = 220m^2
Add Total Surface Area:
Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect
Surface Area = 24 + 24 + 132 + 176 + 220
Surface Area = 576 m^2
3.
Surface Area of Prism Formula:
Triangle Formula: Area = 1/2 * Base * Height
Left Triangle: Area = 1/2 * 9yd * 4yd = 1/2 * 36 = 18 yd^2
Right Triangle: Area = 18 ydm^2
Rectangle Formula: Area = Length * Width
Top Rectangle: Area = 12yd * 8yd = 96yd^2
Middle Rectangle: Area = 12yd * 5yd = 60yd^2
Bottom Rectangle: Area = 12yd * 9yd = 108yd^2
Add Total Surface Area:
Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect
Surface Area = 18 + 18 + 96 + 60 + 108
Surface Area = 300 yd^2
I am not sure if there is a short cut.
