This question cannot be answered sensibly. A cu ft is a measure of volume, with dimensions [L3]. A pound is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
As a simple mental exercise consider a cu ft of air and a cu ft of water. They will have very different weights.
1 cu. yd of cured concrete is about 3600lbs. 1 cu. ft of cured concrete is about 134 lbs. (rounded up) 4 ft x 4 ft x 5/6 ft = 13 1/3 cu. ft 13 1/3 cu. ft = 1787lbs (rounded up)
10 pounds
48 foot trailer: 3000 cu. ft. or 30,000 lbs 53 foot trailer: 3400 cu. ft. or 34,000 lbs.
18 sq m = 193.75 sq ft = 27900 sq in at 1 inch deep = 27900 cu in = 16.15 cu ft sand weighs 100 lbs/cu ft You need 100 x 16.15 = 1615 pounds or 16.15 cu ft = 0.6 yards

The answer is specific to the product in the cu ft. A cu ft of water will be different than that of a cu ft of feathers ETC.

== No!!== 1.5 cu ft of what?! A pound is a unit of weight. A cubic foot is a unit of volume. 1.5 cu ft of concrete weighs much more than 1.5 cu ft of air.
48 foot trailer: 3000 cu. ft. or 30,000 lbs 53 foot trailer: 3400 cu. ft. or 34,000 lbs.
A bag of Quickcrete weighs 80 lbs dry. When water is added it can weigh another 1.5 to 2 lbs. when the water evaporates it will sill retain some water; so, about 80.5 lbs. The Quickcrete covers 1/2 cu ft. or 2 sq. ft. @ 3" thick. 21X20= 420 sq ft X 40.25= 16,905 lbs. or there abouts.
