Oh, so Area would be 5600. So answer is 5600/400.. the depth doesn't matter. Answer is 14

@ParthKohli I think you need to find out if the OP can determine the square footage prior to your just giving him the answer.

parthkohli · Answer

As far as we know, the topsoil is covering the yard in depth. Answer is 14 then.
