1.Calculate the Perimeter of the figure. 7 in 2 in 4 in 2 in 3 in P = 4 + 4 + 7 + 2 + 3 + 2 P = 8 + 9 + 5 P = 17 + 5 P = 22 in

3
2. Calculate the area of the figure. 7 in 2 in 4 in 2 in 3 in A = (4)(4) + (2)(3) A = 16 + 6 A = 22 in 2 6 in 2 16 in 2

Quiz 2-2-11 A cardboard box has the following dimensions: 7.5 ft, 3 ft, 4 ft How many cubic feet of material will the box hold?

5
What is the volume? To calculate the amount of cubic feet, I need to find the volume. The figure is a rectangular prism. To calculate the volume of a rectangular prism, I found the area of the base. The base is a rectangle, so I multiplied the length by the width. I multiplied the area of the base by the height of the prism. A cardboard box has the following dimensions: 7.5 ft, 3 ft, 4 ft. How many cubic feet of material will the box hold? The volume is 90 cubic feet. Rectangular prism Length = 7.5 ft Width = 3 ft Height = 4 ft Volume

9
Review Question A cylindrical coffee can has a radius of 4 in and height of 10 in. Calculate the approximate volume of the can. A.40 in 3 B.120 in 3 C.250 in 3 D.500 in 3

10
Class Work: Changing Dimensions You need your notes. Title the notes: Changing Dimensions I will check your work at the end of class.

11
Changing Dimensions A rectangular prism has a length of 2 ft, width of 3 ft, and height of 4 ft. If the width is doubled, how is the volume affected? Calculate the original Volume Calculate the new Volume Calculate how the volume was affected Draw a picture, illustrating the situation

12
A rectangular prism has a length of 2 ft, width of 3 ft, and height of 4 ft. If the width is doubled, how is the volume affected? Calculate the original Volume Calculate the new Volume

13
A rectangular prism has a length of 2 ft, width of 3 ft, and height of 4 ft. If the width is doubled, how is the volume affected? Calculate how the volume was affected Draw a picture, illustrating the situation Say NO to Oreos The new volume is twice the size of the original volume.

14
Changing Dimensions A cylinder can has a radius of 4 in and height of 8 inches. If the height is cut in half, how is the volume affected? Calculate the original Volume Calculate the new Volume Calculate how the volume was affected Draw a picture, illustrating the situation

15
A cylinder can has a radius of 4 in and height of 8 inches. If the height is cut in half, how is the volume affected? Calculate the original Volume Calculate the new Volume

16
A cylinder can has a radius of 4 in and height of 8 inches. If the height is cut in half, how is the volume affected? Calculate how the volume was affected Draw a picture, illustrating the situation Say NO to Oreos The new volume is half the size of the original volume.

17
Class Work Work with a partner to solve the situations. You will do each problem on a separate piece of paper. You will need to illustrate each situation. You may use a calculator, but remember to show all your steps.
