Question

Help with math Plsss I don't understand how to do this (I got this wrong but I have another try)​

Answer 1

Answer: 920

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

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

Answer 2

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