b) What is the domain of this model?

- AFM (MATH) -
**Reiny**, Sunday, June 24, 2012 at 8:12amlet the side of the square to be cut out be x "

then the

length = 24-2x

width = 14-2x

height = x

volume = x(14-2x)(24-2x)

clearly domain is:

x>0 and 24-2x>0 and 14-2x>0

x>0 and x<12 and x<7

so domain: 0 < x < 7
