2. Tasks for Today Warm Up New Unit: Filling & Wrapping Lesson 1.1-1.2
Begin HW?

3. Warm Up 32 cm x 16 cm x 8 cm SA = 2(896) sq. cm = 1792 sq. cm
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

10. Surface Area
Length, Width, & Height
3. Volume
4. Length and/or Diagonals
5. Length and/or Diagonals

11. Multiply the length by the width
Multiply the length by the width and again by the height

12. 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
SA = 2 ( )
SA = 130 square units
SA = 2 ( )
SA = 76 square units
V = 4 x 5 x 5
V = 100cubic units
SA = 2 ( )
SA = 58 square 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

14. Surface Area Recap
Always label surface area as: units squared or units2 surface area only measures two dimensions (L and W).
Different ways to solve for surface area (SA):
Solve for the area of all six faces and add them all together OR
Solve for the area of three of the faces (for example, top, front, and right), add the areas together, and multiply by two (because there are two pairs of faces that are equivalent) . OR
Double the love method

16. Find All Possible Arrangements
Group Task:
Given 24 cubes and a lab sheet, find 3 possible arrangements.
Fill in the lab sheet as you are working.
Find the volume for each arrangement.
Find the surface area for each arrangement.

17. Possible Arrangements of 24 cubes
Length
Width
Height
Volume
Surface Area
1 inch
24 inches
24 cubic in.
98 sq. in.
2 inches
12 inches
76 sq. in.
3 inches
8 inches
70 sq. in.
4 inches
6 inches
68 sq. in.
56 sq. in.
52 sq. in.

18. Volume Recap Volume is always labeled as:
units cubed or units3 because we use three dimensions to solve for volume.
To find the volume of a polyhedron:
Count how many inch cubes fit in the box. OR
Find the area of the base and multiply it by the height of the polyhedron.
Volume = Bh (B = area of base , h = height) OR
Volume of a Rectangular Prism =
Length x Width x Height
