Answer 3

Right triangular prism surface area =

Area of three rectangles (first having length 15 feet and breadth 10 feet+ Second having length 12 feet and width 10 feet+ Third having length 9 feet and width 10 feet) + Area of upper and lower part in the shape of right triangle with a base of 9 feet and a height of 12 feet

Answer 4

yeah that

Answer 5

thx

Answer 6

\[A=2(10\times15)+(9\times12)+2(\frac{ 1 }{ 2 }\times9\times10)=?\]
I think....
