Rectangular Prism Surface Area Calculator
Calculate rectangular prism total surface area, lateral area, selected base area, face areas, volume, and space diagonal from length, width, and height.
Surface area from length, width, and height
The dominant English intent is a box-shaped rectangular prism with three dimensions. The calculator returns total surface area for all six faces and lateral area for a selected base orientation.
S — total surface area; l, w, and h — length, width, and height.
L — lateral area when length and width form the base; h — perpendicular height.
d — space diagonal across the rectangular prism.
Common uses
| Task | Output |
|---|---|
| Wrapping a box | Use total surface area. |
| Painting room walls | Use lateral area and subtract openings separately. |
| Packaging or coating | Use total area plus a material allowance. |
