First, lets calculate how many square feet you have in the trailer, assuming that you can completely fill the dimensions you've given.
14 ft * 6.4 ft * 8 ft = 716.8 ft³
Now, there are 27 cubic feet to a cubic yard (Why? Because 1 yard = 3 feet, and 3 ft x 3 ft x 3 ft = 27 ft³) so we'll divide 716.8 ft³ by 27 ft³/1 yd³
716.8 ft³ / 27 ft³/yd³ = 26.548 yd³
So, you'll be able to put 26.548 cubic yards of sand into the trailer.
However, I doubt you'll be able to move the trailer once you've loaded it. Sand weighs about 100 pounds per cubic foot, so your 716.8 cubic feet of sand is going to weigh approximately 71,680 lbs.
