The volume of a rectangular prism is the amount of space inside it. To find the volume, you multiply the length ($l$), width ($w$), and height ($h$). The formula is: $V = lwh$. Make sure all measurements are in the same units before you calculate! For example, if the length is in centimeters, the width and height should also be in centimeters.
Let's say you have a rectangular prism with a length of 5 cm, a width of 3 cm, and a height of 2 cm. To find the volume, you would multiply $5 \times 3 \times 2 = 30$. So, the volume of the rectangular prism is 30 cubic centimeters ($cm^3$).
Match the term with its definition:
| Term | Definition |
|---|---|
| 1. Volume | A. The distance from the bottom to the top. |
| 2. Length | B. The measurement of something from end to end. |
| 3. Width | C. The amount of space inside a 3D object. |
| 4. Height | D. The measurement of something from side to side. |
| 5. Rectangular Prism | E. A 3D shape with six rectangular faces. |
Use the words length, width, height, and volume to complete the paragraph.
