<h3>Answer: 920</h3>

=================================================

Explanation:

The front face is a triangle with area of base*height/2 = 15*8/2 = 60 square feet.

The back face is identical to the front face, so we have another 60 square feet.

The left rectangular wall is 20 ft by 8 ft tall. Its area is 20*8 = 160 ft^2

The right slanted rectangular face is 20 ft by 17 ft. Its area is 20*17 = 340 ft^2

Lastly, the bottom rectangle floor is 15 ft by 20 ft to give an area of 15*20 = 300 ft^2

------------------

To summarize so far

  • Front face = 60 ft^2
  • Back face = 60 ft^2
  • Left face = 160 ft^2
  • Right slanted face = 340 ft^2
  • Bottom floor = 300 ft^2

Add up those areas to get the overall surface area.

60+60+160+340+300 = 920

I may be wrong but I think the answer should be 920ft squared. Maybe wait for someone else to confirm this. Good luck!
