Answer 1

Total Area =
`104+16\,√(13)`

Explanation:

If T.A. stands for Total Area, then we need to add the area of two equal right angle triangles of base 6' and height 4', which give : 2 * (6' * 4'/2) = 24 square feet. tothe area of three rectangles (the lateral faces of this triangular base prism):

`(8')*(4')+(8')*(6')+(8')*(√(6^2+4^2))= 32+48+8\,√(52) =80+8\,*\,2\,√(13)=80+16\,√(13)`

Therefore the total area of the prism is:

`24+80+16\,√(13) =104+16\,√(13)`
