Define co-efficient linear, superficial and cubical expansion of a solid and establish a relation between them .

Define co-efficient of linear and cubical expansion and establish a relation between them . The length of a copper wire is measured 40 cm by a metal scale when both are at the temperature of 25^@C . What would be the length of wire measured by the same scale when both are at 55^@C ? (alpha "for metal" = 1.1 xx 10^(-7) @C^(-1) and alpha for copper = 1.7 xx 10^(-7)@c^(-1))
