Homework Statement
A solid copper cube has an edge length of 87.0 cm. How much pressure must be applied to the cube to reduce the edge length to 85.7 cm? The bulk modulus of copper is 1.4 multiplied by 1011 N/m2.
Homework Equations
Vcube= s^3
F/A=(B x deltaV)/V
p=F/A
p=(B x deltaV)/V
The Attempt at a Solution
V= (.870m)^3= .659m^3Vn= (.857m)^3= .629m^3
deltaV= V-Vn= .03m^3
p=(1.4e^10N/m^2)x(.03m^3)/(.659m^3)= 6.37e^9N/m^2This is apparently not the answer?
