Calculate the change of volume that occure when a steel bearing with an initial volume of 1.8cm^3 is heated from 20°C to 80°C.
Tried to use the formula DeltaV/Vinitial=Beta×DeltaT but kept getting the wrong answer though my maths could be off?

so, show us your numbers, and maybe we can tell what went wrong.

I got DeltaV=(1/12×10^6k)(8020)(1.8cm^3)
=1.296×10^3cm^3
The answer Im supposed to be getting is 3.9×10^3cm^3? 
for steel coef of VOLUMETRIC expansion is
about 33 *10^6 to 39*10^6 depending on composition of the steel. You used I suspect 1.13 *10^6 which is more like the LINEAR coef
