Volume = 40*8*8.5 cubic feet = 2720 cubic feet
Assuming the container has rectangular cross-section, Volume=length X width X depth. V=lwd=(20ft)(7ft)(7ft)=980 cubic feet
depends how wide and high it is. Cubic footage is a measure of volume and you thus need all three dimensions
3,000 cubic feet
4000 cubic feet.
4200 cubic feet
