Mathematics 20-3 Module 7

Module 7: Volume and Capacity

 

Lesson 4: Applying Volume and Capacity Formulas

 

Focus

 

People wouldn’t survive without water. Water tanks are used around the world to store water and help create enough pressure to move the liquid to each person in the system. As you can see from the photos, water towers can come in a variety of different shapes. Can you identify any cylinders, cones, or spheres in the towers pictured?

 

Most objects are not pure spheres, pyramids, cones, cylinders, or prisms. Instead, objects are often combinations of many shapes. In this lesson you will apply volume and capacity formulas to a variety of practical problems, including composite figures.

 

These photos represent many varieties of water tanks from around the world.
