$\overline{){\mathbf{Pressure}}{\mathbf{=}}\frac{\mathbf{Force}}{\mathbf{Area}}}$

$\overline{){\mathbf{Force}}{\mathbf{=}}{\mathbf{mg}}}$

where m = mass and g is the acceleration due to gravity: 9.8 m/s2

A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of 3.0 x 4.1 in contact with the floor. The total mass of the shelves plus the books stacked on them is 266 kg.

Calculate the pressure in pascals exerted by the shelf footings on the surface.
