In this lesson, we will learn:

- That cubic measure refers to the cubed units that are used to measure volume
- How to count the cubic measure of volumes for a single layer of unit cubes
- How to count the cubic measure of volumes for multiple layers of unit cubes

**Cubic measure**refers to the**units**we use to measure**volume**- A
**unit cube**is a cube with a measure of__1 unit__on each side - Units can be in
**metric units**(i.e. m^{3}, cm^{3}, mm^{3}) or other**customary units**(i.e. ft^{3}, in^{3}, yd^{3})

- Recall that different
**dimensions**(1-dimensional, 2-dimensional, 3-dimensional) correspond to**geometric properties**of shapes (**perimeter, area, volume**) as well as their units:

- For the 3D property of shapes (
**volume**), we use cubes to measure the amount of__space occupied by a 3D shape__

- The
**cubic measure**of**volume**can be thought of as the number of__unit cubes__that can fit in a 3D shape - If there is only
__one layer__of unit cubes, simply**count**the number to find the cubic measure.

- If there are multiple layers of unit cubes:
**count**the number in__one layer__and**multiply**by the__number of layers__there are in the same direction.

- 1.
**Counting Cubic Units of Rectangular Prisms**

Count to find the cubic measure of each 3D shape. The unit is specified next to the shape.a)

edges are in centimeters (cm)b)

edges are in millimeters (mm)c)

edges are in kilometers (km)d)

edges are in yards (yd) - 2.
**Counting Shortcuts for Cubic Units of Rectangular Prisms**

Find the cubic measure of each rectangular prism.a)

edges are in meters (m)b)

edges are in inches (in)c)

edges are in feet (ft).d)

edges are in centimeters (cm) - 3.Given the front view of the rectangular prism and the total cubic measure (volume), complete a 3D drawing.a)Front View: Volume = 14 in
^{3}b)Front View: Volume = 30 yd^{3}c)Front View: Volume = 24 ft^{3} - 4.
**Same Cubic Measures in Different Configurations**

You will be tasked with building a regular rectangular prism with cubic centimeter blocks.a)If the total cubic measurement must be 8cm^{3}, drawdifferent rectangular prisms with this volume.__three__b)If the total cubic measurement must be 12cm^{3}, drawdifferent rectangular prisms with this volume.__four__c)If the total cubic measurement must be 18cm^{3}, drawdifferent rectangular prisms with this volume.__five__
