Volume is the measure of the amount of space occupied by a three-dimensional object. It is typically measured in cubic units, such as cubic centimeters or cubic meters.

There are different formulas for calculating the volume of different three-dimensional shapes:

**Cube or rectangular prism:**V = l * w * h, where l is the length, w is the width, and h is the height.**Cylinder:**V = π * r^{2}* h, where π (pi) is approximately 3.14, r is the radius of the base, and h is the height.**Sphere:**V = (4/3) * π * r^{3}, where π (pi) is approximately 3.14 and r is the radius.**Cone:**V = (1/3) * π * r^{2}* h, where π (pi) is approximately 3.14, r is the radius of the base, and h is the height.

Volume is typically measured in cubic units, such as cubic centimeters (cm^{3}) or cubic meters (m^{3}).

Here are some practice problems to help you understand how to calculate volume:

- Find the volume of a cube with side length 5 cm.
- Calculate the volume of a cylinder with a radius of 3 cm and a height of 8 cm.
- Determine the volume of a sphere with a radius of 6 cm.
- Find the volume of a cone with a radius of 4 cm and a height of 10 cm.

Remember to use the appropriate formula for each shape and substitute the given values to calculate the volume.

Volume is an important concept in geometry and is used to measure the amount of space occupied by three-dimensional objects. Understanding the formulas for calculating volume and practicing with different shapes will help you master this concept.

Connections to the Grade 7 Focal Points (NCTM)

Measurement and Geometry: Students connect their work on proportionality with their work on area and volume by investigating similar objects. They understand that if a scale factor describes how corresponding lengths in two similar objects are related, then the square of the scale factor describes how corresponding areas are related, and the cube of the scale factor describes how corresponding volumes are related. Students apply their work on proportionality to measurement in different contexts, including converting among different units of measurement to solve problems involving rates such as motion at a constant speed. They also apply proportionality when they work with the circumference, radius, and diameter of a circle; when they find the area of a sector of a circle; and when they make scale drawings.
