I'm assuming length is depth.
A rectangular solid has 6 sides, so the total area will simply be 6 times the area of one side.
The area of one side is the area of square which is w*h.
The volume of a rectangular solid is l*w*h.
From Google,
"The lateral area is the surface area of a 3D figure, but excluding the area of any bases."
So if you were to take the solid and flatten it, you would get the area of four sides.
Lateral Area = 4*h*w

Whoops, I read those numbers wrong.
The area of two sides will be l*h and the other four will be w*h.
So the total area = 2(l*h) + 4(w*h)
Sorry about that :S
