Example 13.6.2

A solid copper cube has an edge length of 85.5 cm. How much pressure (in N/m^{2}) must be applied to the cube to reduce the edge length to 85.0 cm? The bulk modulus of copper is 1.4 x 10^{11} N/m^{2}.

where we have substituted volume of the cube = (edge length)^{3}

and DV = |V_{f} - V_{i}|
