Cuboid Calculator
Calculator and formulas for calculating the volume and surface of a cuboid
This function calculates the volume, the surface area and the diagonal of a cuboid. A cuboid is a polyhedron with six rectangles as faces. The opposite faces are parallel and of equal size.
To perform the calculation, enter the length of the three sides and click the 'Calculate' button.

Properties of a cuboid
A cuboid is a geometric figure consisting of six rectangles, two of which are parallel and opposite each other. The size of a cuboid is always clearly determined by three details.
Formulas for a cuboid
Volume (\(\small{V}\))
\(\displaystyle V=a · b · c\)
Surface (\(\small{S}\))
\(\displaystyle S= 2 ·((a · b) + (a · c) + (b · c)) \)
Diagonal (\(\small{d}\))
\(\displaystyle d=\sqrt{a^2 · b^2}\)
Diagonal (\(\small{e}\))
\(\displaystyle e=\sqrt{a^2 · b^2 · c^2}\)
