Cubic Units
Name cubic centimeters, inches, feet, and meters, and choose the sensible one.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 3
- Cubes come in many sizes. A cube with sides 1 centimeter long has a volume of 1 cubic centimeter. That's about the size of a sugar cube.
- A cube with sides 1 inch long is 1 cubic inch. A cube with sides 1 foot long is 1 cubic foot. A cube with sides 1 meter long is 1 cubic meter, big enough to sit inside.
- Choose a cube that fits the job. You'd measure a shoebox in cubic inches, a bedroom in cubic feet, and a swimming pool in cubic meters.
- Watch the words. Length uses plain units, area uses square units, and volume uses cubic units, because each one measures something different.
Georgia's K-12 Mathematics Standards:
- 5.GSR.8.3 — Investigate volume of right rectangular prisms by packing them with unit cubes without gaps or overlaps. Then, determine the total volume to solve problems.
- 5.GSR.8.4 — Discover and explain how the volume of a right rectangular prism can be found by multiplying the area of the base times the height to solve authentic, mathematical problems.
