New Unit- Filling & Wrapping
Lesson (Finding Volume & Surface Area)
Begin HW?

3. Warm Up
To test your understanding of volume and surface area, consider the following…
32 cm x 16 cm x 8 cm
SA = 2(896) sq. cm
= 1792 sq. cm
Vol = 4,096 cubic cm

4. Things to Know! Many packaging involves rectangular prisms.
It is helpful to know the properties of rectangular prisms
We will learn about the MOST important properties of rectangular prisms
Learning about the properties will help you DEVELOP strategies for working with nonrectangular prism.

5. How do you calculate the surface area & volume of a rectangular prism?

Vol = L x W x H
Vol = 10 x 15 x 8
Vol = 1,200 containers

13. Vol = Multiply the all three dimensions – L x W x H
pg. 10
SA = 2 ( )
SA = 130 square units
SA = 2 ( )
SA = 76 square units
SA = 2 ( )
SA = 58 square units
V = 4 x 5 x 5
V = 100cubic units
V = 4 x 5 x 2
V = 40 cubic units
V = 4 x 5 x 1
V = 20 cubic units
SA – Find the area of the front, top and side. Then add them together and multiply by 2 to find the SA for all six faces.
Vol = Multiply the all three dimensions – L x W x H
