How do we find the volume of a triangular pyramid ?
1 Answer
Use the formula for the volume of a triangular pyramid:
Explanation:
Let's take an example triangular pyramid and try this formula out. Let's say the height of the pyramid is 8, and the triangular base has a base of 6 and a height of 4.
First we need
(Note: don't get this base confused with the base of the whole pyramid- we'll get to that later.)
So we just plug in the base and height of the triangular base:
Okay now we plug this area
There we go- now if you're given area of the triangular base it's even easier, just plug it and the pyramid height directly into the formula.
