Volume

Volume

by Mr. Winters

Objective

• To provide an understanding of the definition of volume

• To teach you how to calculate the volume of an three-dimensional object

What is Volume

is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

How is Volume calculated?

Volume is calculated by multiplying three different dimensions which are: Length, Width, and Height.

Because we are multiplying three different dimensions, the unit measurement will be raised to the third power or CUBED.

Formula for Volume of a Cube

The formula for Volume of a Cube is: V = L x W x H

Multiple Choice

True or False: The unit measurements for volume must be cubed?

• True

• False

Example

Use the following measures of a cube:

L = 6 mm

W = 3 mm

H = 10 mm

If we are to find the volume of this cube we would simply multiply 6 x 3 x 10 to get the answer. The answer would be 180 mm³

Multiple Choice

What is the volume of a cube with the following dimensions: L=10ft, W=10ft, W=10ft

• 100 ft^3

• 1000 ft³

• 1000 ft²
