What is the formula for finding area of a rectangular prism?

Answer 1

Length*Width*Height.

Nice try, but that would be the volume. The question asked for the area.

Here is the correct answer:

Area = (2 X length X width) + (2 X (length + width) X height)

* * * * *

or equivalently,

2*(L*W + W*H + H*L) I think that is easier to remember.

Answer 2

times the length and height of the square and then times the length and height of the rectangle and then add them up
