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)

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

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.

Magnolia has a heat value similar to Willow. It is not as good as Oak, but better than Poplar. It will need seasoning (drying), and will weigh about 35 lbs per cu ft when dry, compared to Oak at 57 lbs per cu ft. Not bad wood, not the best.
