Math calculator
Rectangular Prism Calculator
Calculate rectangular prism volume, surface area, and space diagonal.
Formula
Rectangular prism
Volume = length x width x height; surface area = 2(lw + lh + wh)
6 by 4 by 3 gives volume 72.
FAQs
What is the space diagonal?+
It is the straight-line distance between opposite corners of the prism.
What units are used?+
Use one consistent length unit; volume is in cubic units.
