I removed this section, didnd't seem very clear or useful as written. Tom Ruen 22:41, 12 September 2006 (UTC)
To get the surface area of a triangular prism, you need to find the base area(0.5*bh) of the triangle. This is known as A1 in the following formula. The rectanges are known as A2, A3, and A4 in this formula.
The formula for an equilateral triangular base in the prism is:
- A1×2+A2×3
The formula for an isosceles triangular base in the prism is:
- A1×2+A2×2+A3
The formula for a scalene triangular base in the prism is:
- A1×2+A2+A3+A4
To get the volume of a triangular prism you need to find the base area of the triangle(0.5*bh) and the length of the prism.
The General formula that is commonly used is: Base Area*length or 0.5*base*height*length
- Yeah that's not as clear as it could be. I don't think it's very good that this article has been left without a volume formula though.
- I've tried to add one in again. Something a bit more succinct than the above. Needs work still though. Ideally someone needs to draw a little diagram showing the width height length measurements. I suppose talking about width implies that the prism would be lying on it's side, unlike in the top-right diagram. -- Nojer2 12:25, 15 December 2006 (UTC)
