Just remember folks...the flu (influenza) is an upper respiratory infection...nausea and vomiting are not symptoms of the flu . ...So many times people say they have the flu but it really is not..
Length x width x height equals volume. * * * * *. But only if the object in question is a cuboid (rectangular prism). Length*Width*Height for a sphere, for example, does not equal its volume.
H = height (how tall it is), D = depth (how far out it comes from the wall) , L = length (how long it is). If there are no letters associated with the measurements, then the most general format for listing measurement is Length x Depth x Height. If it is a workbench, I would assume it would be 48 inches long across, 23.75 inches deep, and 37.5 inches tall. Everyone else is right, that will make for a good work surface.
