Lesson Topic: The Formula for Volume & Volume in the Real World

Lesson Objective: I can…I can develop, understand, and apply

formulas for finding the volume of right rectangular prisms and cubes

I can understand that volume is additive and apply volume formulas to determine the volume of composite solid figures in real-world contexts.

I can apply volume formulas to find missing volumes and missing dimensions.

Review of Lesson 11-12

To determine how many fractional unit cubes fit in a right

rectangular prism:

1. Multiply each dimension by the denominator of the fractional size of the unit cube (length,

width, & height)2. Multiply lwh

Example 1

Determine the volume of a rectangular prism with a base area of

and a height of .

Example 2

Example 3
