Rectangular Prism Volume Calculator
Calculate rectangular prism volume, surface area, space diagonal, total edge length, base area, and lateral area from length, width, and height.
Enter length, width, and height in the same unit. Changing the unit converts all three fields.
Volume from length, width, and height
The dominant English intent is length times width times height. Competitor calculators also show surface area and diagonal, so this page includes those values without changing the simple three-input workflow.
l, w, and h are length, width, and height.
d is the space diagonal.
When to use it
| Task | Output to use |
|---|---|
| Box capacity | Volume. |
| Wrapping or coating | Surface area. |
| Maximum internal straight-line span | Space diagonal. |
