A rectangular block of mass m m\,m and weight W W\,W rests on a flat, horizontal table top. The area of the bottom face of the block in contact with the table is AAA.
Which of the following equations correctly expresses the pressure p p\,p exerted by the block on the table?
p=WAp = \frac{W}{A}p=AW
p=mAp = \frac{m}{A}p=Am
p=W×Ap = W \times Ap=W×A
p=AWp = \frac{A}{W}p=WA
