the linear expansively of the material of a cube is 12*10-6k. if the length of each side of the cube is 10cm,find the area of one face of the cube and the volume of the cube when its temperature is raised by 30k

Answer 1

as with all geometric objects, the volume grows as the cube of the linear scale factor.

I assume your coefficient is 12*10^-6 cm/°K (can't quite tell from your notation). Anyway, if the linear size grows by 1.0002, then the area grows by 1.0002^2 and the volume grows by 1.0002^3, so multiply the base values by those scale factors.
