How many sheets of plywood would it take to roof a bldg 40x60 with 412 pitch?
If a 412 pitch means a one third pitch then 20% needs to be added on to the area to be covered. So, for a 40ft x 60ft building, the total area to be covered is 40x60 = 2400 sq ft. Adding 20% or 480 sq ft this comes to 2880 sq ft. Next work out the area of the plywood sheets. Lets say 10ft x 5ft or 50 sq ft. So the total number of sheets is total area needed divided by the area of the sheets. That works out to 2880/50 = 57.6 or 58 sheets. A useful table for working out the area of a roof for various pitches is at the web link below.

Volume of triangular prism?
I think first you calculate the area of the triangular face. If you forgot that's ok. The formula is A= bxh divided by 2 which is the same as the area of a triangle is base multiplyed by height and divided by two. Then you need to know the length of the prism(the length of the rectangle)and multiply them together. So your calculation should look like this: Triangular face- A=bxh divided by 2 let's say that the base of the triangle is 5 cm and the height is 12cm Length of prism- let's say the length is 25 cm A=bxh divided by 2 A=5 x 12 divided by 2 A = 20 divided by 2 A = 30 cm squared 30 x 25 = 750cm squared( little 2)
