A package with square ends has a combined length and girth (girth is the perimeter of a cross section) of 120 in. The surface area of the entire package is 3600 sq. in.

Determine the dimensions of thr package. s in.*s in.*l in.

one solution is: 11.08in*11.08in*75.68in.

find the other solution

hint: if 4S + length=120, then the length=120-4S

Solution:

4S + length=120

And

S^2+4S*length=3600

So

S=12

Length=72

Solution is 12*12*72
