Answer 19

Look at what you got.
1 ea. front panel 8 X 13 sq yd
2 ea triangular sides at 1/2 X 5 X 12
1 ea bottom 5 X 8
1 ea back 12 X 8

Do you see that is what you are dealing with.

Answer 20

Figure the area of these 5 figures, add them, and you will have the total surface area.

Answer 21

Front panel: 8 X 13 = 104 Sq Yd
side panels 1/2 X 5 X 8 = 20, but there are 2 ea so that is 40 more sq yds.
bottom: 5 X 8 =40 sq yd.
back: 12 X 8 = 96

Add em up. Be careful.

Answer 22

@radar i got 280 :/

Answer 23

I erred on the dimensions of the side panels 30 each or a total of 60 sq yd. I don't think the 280 sq yd is correct more like 300
