Answer:
2800ft^2
Step-by-step explanation:
Find the surface area of each side (some have the same area on two sides so it says x 2 because there are two sides with the same area)
top of triangles: 10x25= 250
triangle shaped sides: 15x10= 150
top and bottom of rectangular prism: 36x10x2=360x2=720
tiny side of rectangular prism: 10x20=200
vertical sides of rectangular prism: 20x36x2=720x2=1480
add the answers together to get the total surface area is 2800ft^2
Hope this helps! :)
