5. 96 ft³
6. 108 cm³
Explanation:
I will answer in spite.
5. To find the volume, seperate the figure into two separate rectangles (one long one along the bottom, and one small one sitting on top).
The volume of rectangle one is 4ft × 9 ft × 2ft = 72 ft³.
The volume of rectangle two is 4ft × 3ft × 2ft = 24 ft³.
72 ft³ + 24 ft³ = 96 ft³.
6. Patty treated the figure as two separate rectangles with the dimensions 2x3x11 and 2x3x10, not taking into account the space where the rectangles meet.
She should have calculated (2x3x11) + (2x3x7), which is 108 cm³.
You're welcome Mr. Harvard.
