The Surface Area of a Cuboid calculator computes the surface area of a cuboid based on the length, height and width (see diagram).
INSTRUCTIONS: Choose the preferred units and enter the following:
(L) This is the length of the cuboid.
(H) This is the height of the cuboid.
(W) This is the width of the cuboid.
Cuboid Surface Area (A): The area (A) is returned in square meters. However, this can be automatically converted into many other area units via the pull-down menu.
