thermodynamic question

What pressure increase is needed to make a cubic block of magnesium metal retain its initial volume while it is being heated from 0 to 50C? The average linear expansion coefficient αL = 2.5x10-7 K-1 , the isothermal compressibility factor β = 2.95x10-10 (N/cm2 )-1 .

The hint is in the fact you are asked about a cubic block.

Think how would you convert linear forces to pressures over the area of a block face.
