Exercise 40 Page 846

Check the four formulas. What do they have in common? What is different?

See solution.

Practice makes perfect

Let's start by writing the formulas to find the volumes of pyramids, cones, prisms, and cylinders.

Volume Formulas
Pyramid	V = 1/3Bh
Cone	V = 1/3Bh
Prism	V = Bh
Cylinder	V = Bh

As we can see, finding the volume of pyramids and cones is exactly the same as finding the volume of prisms and cylinders except that we need to multiply the answer by one-third.
