Using the formula's, you can find out the answer:
Rectangular Prism- LWH
Pyramid- XYZ/3
1. Make up numbers for the Variables: X=6, Y=3, Z=8
2. Find the volume for the Rectangular Prism: 6 x 3 x 8 = 144
3. Find the Volume for the Pyramid: 6 x 3 x 24 = 432 (Because there is a times 3 there), then, divide by 3, because to find the Volume, you need to divide by 3, to get 144.
Hope this helped. If you need a more detailed Explanation, comment and I'll add to this!
