# Mobile Phones

## Worksheet Description

This worksheet features a set of word problems focused on calculating the volume of objects associated with mobile phones. The items described include a smartphone, a power bank, a mobile phone case, and related accessories like a Bluetooth speaker and a charger. Each problem provides the dimensions of these objects in various shapes, such as rectangular prisms, cylinders, and rectangular sheets, and asks students to calculate their volume in cubic centimeters or inches.

The worksheet is intended to teach students how to calculate the volume of different three-dimensional objects by applying geometric formulas for volume. It specifically targets the recognition of shapes and the application of volume formulas in a contemporary context that students can easily relate to. This exercise aims to improve students’ mathematical and problem-solving skills, as well as their ability to visualize geometric shapes and understand their properties. Additionally, it helps students become more familiar with the metric and imperial units of measure, an essential skill for understanding real-world dimensions and sizes.

**Example Problems**

1. A smartphone has a rectangular shape with dimensions 6 centimeters by 3 centimeters by 0.5 centimeters. Calculate the volume of the smartphone in cubic centimeters.

2. A cylindrical power bank has a radius of 2 inches and a height of 4 inches. Determine the volume of the power bank in cubic inches.

3. A mobile phone case is shaped like a rectangular prism with dimensions 5 inches by 3 inches by 0.2 inches. Calculate the volume of the phone case in cubic inches.

4. A cylindrical Bluetooth speaker has a radius of 3 centimeters and a height of 10 centimeters. Determine the volume of the speaker in cubic centimeters.

5. A tablet computer has a rectangular shape with dimensions 8 inches by 5 inches by 0.3 inches. Calculate the volume of the tablet in cubic inches.

6. A mobile phone battery is shaped like a cylindrical rod with a radius of 1 centimeter and a length of 6 centimeters. Determine the volume of the battery in cubic centimeters.

7. A smartphone screen protector is a thin rectangular sheet with dimensions 4 inches by 2 inches by 0.001 inches. Calculate the volume of the screen protector in cubic inches.
