: I am building a speaker box for my truck, and need to find the formula to find the volume for a triangle. You have a height, width, and length. I know you use
: a squared+b squared = c squared to find the dimension of the hyp. but can't find out how to find the volume for the triangle. Please help me if you can in any way.

I am assuming you have a triangular box - i.e. say you can stand it up so that the bottom is a triangle - top is a triangle (same shape and size as the bottom one. This box has three other sides that are rectangles - each of which has one side of the trianle(s) as one side and the height of the box as other side. (If I could draw here - I would not have to say all these words..)

Now

Area of the right angled triagle = 1/2 * b * p
(b and p are the sides of the right angled triangle - these are not hypotenuse. Assume

height of the Box = H

So the volume of the box = 1/2 * b * p * H
