A cube of solid aluminum has a volume of 1.00 m^3 at 20 degree C. What temperature change is required to produce a 100-cm^3 increase in the volume of the cube?

I know you are supposed to use: DeltaV=Beta*Vo*DeltaT. But I don't know what Beta is and the ones I have found have given me way wrong answers.

1. 1 m^3 = (10^2)^3 = 10^6 cm^3
so 100cm^3 = 10^-4 m^3
so
deltaV/Vo = 10^-4/1 = 10^-4
so
10^-4 = Beta (delta T)
delta T =10^-4/(7.2*10^-5) = 10/7.2
