Introduction to Solving Problems Using Volume and Surface Area
Josie is a kindergarten teacher and wants to make felt toys for her students. These felt toys will be cylinders, meant to replicate cans. She wants to put the felt toys in the new play kitchen in her classroom. To find the amount of felt she needs, Josie will need to calculate the surface area of the cans she plans to make. This chapter will explain how to find surface area of different objects, including cylinders.Learning Outcomes
By the end of this section, you will be able to:- Find volume and surface area of rectangular solids
- Find volume and surface area of spheres
- Find volume and surface area of cylinders
- Find volume of cones
