What is the lateral area, total area, and volume of a rectangular solid whose l=7, w=6, & h=2?

Answer 1

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

Answer 2

THANK YOU. THIS REALLY HELPED =]

Answer 3

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
