Volume Study Guide
What is Volume?
Volume is the amount of space occupied by a 3D object. It is measured in cubic units, such as cubic meters (m3) or cubic centimeters (cm3).
Formulas for Calculating Volume
Here are some common formulas for calculating the volume of different 3D shapes:
- Cube: V = s3, where s is the length of a side of the cube.
- Rectangular Prism: V = l * w * h, where l is the length, w is the width, and h is the height of the prism.
- Cylinder: V = πr2h, where r is the radius of the base and h is the height of the cylinder.
- Sphere: V = (4/3)πr3, where r is the radius of the sphere.
Units of Volume
Volume can be measured in various units, depending on the context. Some common units of volume include cubic centimeters (cm3), cubic meters (m3), liters (L), and milliliters (mL).
Practice Problems
Calculate the volume of the following objects:
- A cube with side length 5 cm.
- A rectangular prism with length 10 cm, width 4 cm, and height 3 cm.
- A cylinder with radius 2 cm and height 8 cm.
- A sphere with radius 6 cm.
Conclusion
Understanding volume and how to calculate it is important for various real-world applications, such as measuring the capacity of containers, determining the amount of material needed for construction, and more.

Connections to the Grade 6 Focal Points (NCTM)
Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
