Using Linear, Square, and Cubic Measure Appropriately
Learning Outcomes
- Understand the difference between linear, square, and cubic measure
example
For each item, state whether you would use linear, square, or cubic measure: 1. amount of carpeting needed in a room 2. extension cord length 3. amount of sand in a sandbox 4. length of a curtain rod 5. amount of flour in a canister 6. size of the roof of a doghouse. Solution1. You are measuring how much surface the carpet covers, which is the area. | square measure |
2. You are measuring how long the extension cord is, which is the length. | linear measure |
3. You are measuring the volume of the sand. | cubic measure |
4. You are measuring the length of the curtain rod. | linear measure |
5. You are measuring the volume of the flour. | cubic measure |
6. You are measuring the area of the roof. | square measure |

[ohm_question]146501[/ohm_question]Perimeter and Area
The perimeter is a measure of the distance around a figure. The area is a measure of the surface covered by a figure.[latex]\begin{array}{c}\text{Perimeter}=4\text{ inches}\\ \text{Area}=1\text{ square inch}\end{array}[/latex]
When the ant walks completely around the tile on its edge, it is tracing the perimeter of the tile. The area of the tile is [latex]1[/latex] square inch.example
Each side of two square tiles is [latex]1[/latex] square inch. Two tiles are pushed side by side and shown together below. 1. What is the perimeter of the figure? 2. What is the area?Answer: Solution 1. The perimeter is the distance around the figure. The perimeter is [latex]6[/latex] inches. 2. The area is the surface covered by the figure. There are [latex]2[/latex] square inch tiles so the area is [latex]2[/latex] square inches.
