8 Activity I: Team Problem-Solving: Rectangular Prisms Problem 1: A rectangular tank, 30 cm long and 20 cm wide, is filled with water to a depth of 8 cm. When a stone was put in, the water level rose to 11 cm. Find the volume of the stone. (Assume that the stone was completely under water.) Problem 2: A rectangular tank, 32 cm long and 30 cm wide, contained some water and a stone. When the stone was taken out, the water level dropped by 2 cm. Find the volume of the stone. (Assume that the stone was completely under water.) Office of Academics and Transformation, Mathematics Page 6 of 16

Activity II: Team Problem-Solving: Cylinders How Many Jelly Beans Fill A One-Liter Bottle? A one-liter bottle in the shape of a cylinder is filled with jelly beans.

11 Activity II: Team Problem-Solving: Cylinders How Many Jelly Beans Fill A One-Liter Bottle? A one-liter bottle in the shape of a cylinder is filled with jelly beans. An examination of a jelly bean reveals that it is approximately the size of a small cylinder that measures about 2 centimeters long by about 1.5 centimeters in diameter. The irregular shape of jelly beans result in them not being tightly packed; therefore, approximately 80% of the volume of the bottle is filled. About how many jelly beans fill the one-liter bottle?

13 Reinforcement Activity Identify the choice that best completes the statement or answers the question. 1 A local theater company is redesigning its popcorn containers. The current container is a rectangular prism, and the new container will be a right, circular cylinder. The dimensions of the containers are shown below. Which of the following is closest to the difference in volume between the cylinder and rectangular prism? A 237 cm 3 C 3693 cm 3 B 3456 cm 3 D 7149 cm 3 Office of Academics and Transformation, Mathematics Page 11 of 16

2. A construction company has a contract to build a memorial. The memorial will be a right, circular, cylinder with a radius of 12 yards and a height of 10 yards.

14 2. A construction company has a contract to build a memorial. The memorial will be a right, circular, cylinder with a radius of 12 yards and a height of 10 yards. The entire interior of the cylinder will filled with steel. How much steel will be needed to fill the memorial, to the nearest cubic yard?

15 3. Mrs. Washington's class is collecting cans of soup for a local food drive. The class plans to package the cans in boxes before distributing them. They want to find the volume of a soup can so they figure out how many will fit in each box. A diagram of one soup can is shown below. What is the best approximation of the volume, in cubic inches, of the soup can in the diagram? F in 3 H in 3 G in 3 I in 3 Office of Academics and Transformation, Mathematics Page 13 of 16
