ok so find volume of box and find how many volumes of box will be at least volume of closet
V=LWH
Vbin=20*18*14
Vbin=5040 in^3
Vcloset=60*36*72
Vcloset=155520 in^3
how many Vbins=1Vcloset?
how many 5040=155520
divide both sides by 5040
how many=30.8
round up
31 bins will hold all stuff
but only 30 can fit in closet, but will not hold al stuf
