You need 75 cubic foot - which dry would weight roughly 6750 pounds (depending on gravel content) and that puts you at just about 3.375 (or 3-1/3) tons! So three one-ton loads would get you surrounded by the ballpark, as it were. ;)
A small dump truck carry about 6 yard when full and your sand would also be about 2.8 cubic yard, so one 1/2-load of sand in a dump truck would also do the trick.
