INSTRUCTIONS: Choose units and enter the following:
Total Area (A): The calculator computes the area in square feet. However, this can be automatically converted into other area units via the pull-down menu. Note, this does not include the ceiling or floor.
The formula to compute the surface area of walls in a room is:
`A = (2*L*H + 2*W*H)`
