Formula
V = l×w×h; SA = 2(lw+lh+wh); Diagonal = √(l²+w²+h²); Lateral = 2h(l+w)
- Rectangular Prism (Cuboid) Calculator calculates its result from Height, Length, Width, Wh, Lw, Lh. It uses the formula V = l×w×h; SA = 2(lw+lh+wh); Diagonal = √(l²+w²+h²); Lateral = 2h(l+w). Change any input to recalculate the result instantly.
- The main inputs are Length, Width, Height. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
