Because your right triangle is half of a rectangle, you would multiply one measurement by the other and then divide that by two. Then multiply that by 15 per square meter. Unfortunately, this will UNDER estimate your cost, as the triangular sail's hypotenuse is NOT a straight line. But it'll get you 'in the ballpark'.
-- 5m x 3m = 15 square meters on the floor. -- Another 15 square meters on the ceiling. -- (10 x height of the room) on one pair of walls. -- (6 x height of the room) on the other pair of walls.
That would be a triangular pyramid.
Multiply the length of the prism by the area of the triangular face. How you find the area of the triangular face will depend on what information you have about the triangle: 3 sides, 2 sides and the included angle, 1 side and 2 angles, base and vertical height or any of a number of other sets of data.

If you split it into two right triangles, then each one will have one of the legs = 3.5 meters, and the hypotenuse = 7 meters. Solving for the other leg will give you the height sqrt(3)* 3.5 meters, or approximately 6.062 meters.

I heard one of the pyramid is 61 meters/side and it was over 30 meters height. I'm not sure about the other two but they look simillar
It is a pyramid
You muliply the base times the height of one of the triangles in the trianagular prism (both triangles will be similar, proportional, and equal, and you divide that number by two or multiply that number by 1/2, then you multiply that number times the height or length of one triangle's end to the other triangle's end of the triangular prism to obtain your final volume. The formula is as follows. V=1/2(b*h)(height)

Yes, the number 21 is indeed a triangular number. Other triangular numbers are 6,10, and 15.
