1. 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.

2. 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
