# Exercise

## Worksheet Description

This worksheet contains a series of word problems centered around calculating the volume of various objects, which are related to fitness or exercise equipment. The items mentioned include a cylindrical water bottle, a rectangular dumbbell, a gym locker, a soccer ball, and other objects typically found in a gym or related to physical activity. Each problem describes the dimensions of the object and asks the student to calculate the volume, indicating that the student will need to apply different formulas to find the volume of cylinders, prisms, spheres, and other shapes.

The worksheet is designed to teach students how to apply geometric formulas to calculate the volume of different three-dimensional objects. It encourages the practical application of mathematics in real-life scenarios, such as a gym setting, reinforcing the concept that geometry is not just theoretical but also has tangible uses. By working through these problems, students enhance their understanding of volume and become familiar with the mathematical procedures for different shapes. Additionally, it reinforces unit conversion and spatial reasoning skills by requiring students to work with various units of measurement.

**Example Problems**

1. A gym has a cylindrical water bottle with a radius of 5 centimeters and a height of 20 centimeters. Calculate the volume of water the bottle can hold in cubic centimeters.

2. A fitness enthusiast is using a rectangular dumbbell with dimensions 15 inches by 5 inches by 3 inches. Determine the volume of the dumbbell in cubic inches.

3. A gym locker is shaped like a rectangular prism with dimensions 12 inches by 15 inches by 18 inches. Calculate the volume of the locker in cubic inches.

4. A soccer ball has a spherical shape with a radius of 11 centimeters. Determine the volume of the soccer ball in cubic centimeters.

5. A swimmer is using a cylindrical buoy with a radius of 3 feet and a height of 4 feet. Calculate the volume of the buoy in cubic feet.

6. A runner is filling a conical water bottle with a radius of 6 centimeters and a height of 12 centimeters. Determine the volume of water the bottle can hold in cubic centimeters.

7. A weightlifting plate is shaped like a circular cylinder with a radius of 8 inches and a thickness of 2 inches. Calculate the volume of the weightlifting plate in cubic inches.
