Enter values — the result will show here live.
How to use
- Choose the base type: square or rectangular.
- For square, enter length and height; for rectangle, enter length, width and height.
- You will get the volume, slant height and total surface area.
Note: Volume: V = (1/3) x base area x height. Surface area includes the base and all triangular faces; slant height is found with Pythagoras.
