Directions for finding the volume of a truncated pyramid. (frustum)
Basically a pyramid with the top cut off.

To find the volume of a truncated pyramid use 1/3 base x height of a pyramid and then subtract the portion of the pyramid that is missing.
1/3Bh-1/3Bh but the base and height measurements will be different.
The base areas are pretty easy to find because they are given.
The altitude is a little tricky, but can be solved by setting up proportions in order to find slant height..
Next, I use the Pythagorean Theorem with the slant height in order to find the altitude.
I will repeat this for the smaller base.
Finally I will plug all of these dimensions in
1/3Bh-1/3Bh for the volume of the truncated pyramid.
