An artist wants to create a metal sculpture using a mold so that his artwork can be readily mass produced. he wants his sculpture to be exactly 6 inches tall. should the mold also be 6 inches tall? why or why not?

NO

Explanation:

No the mold should not be of the same size as that of sculpture because the material from which molds is made may shrink or expand depending upon its properties .

For example grey cast iron shrinks on cooling.

We need to make mold bigger in general so that if there is a need of finishing it can be done easily without altering the size of sculpture.
