Basically, you draw a line down from the shortest part straight to the base.. that gives you a rectangle (easy enough to calc volume there).. Then, you have a triangle left.. the formula for the volume is (I believe) 1/2 x base x height x width.. basically, it's 1/2 of the comprable rectangle you would if you took 2 triangles and flipped one over and put them together to make the rectangle.. make sense?

you right on the formula for figuring the volume of the triangle

ya take the top measurement and the bottom add them say 8 and 12 that be 20 divide by 2 so you get 10 then muliply that by height and width. after gettin that number divide by 1728 to get the volume in cubic feet
