1. Bell Ringer 2-2-11 1. Calculate the Perimeter of the figure. 2. Calculate the area of the figure. 7 in 2 in 4 in

2. 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

4. 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
