That depends on what this is a half-cubic foot OF. Feathers? Lead? Helium? It makes a difference.
0ne half cubic foot. One cubic foot is 100 pounds
A half-inch thick sheet of plate steel measuring 4 feet by 8 feet has a volume of 128 cubic feet (4 ft x 8 ft x 0.5 ft). Steel has a density of approximately 490 pounds per cubic foot. Therefore, the weight of the sheet would be about 62,720 pounds (128 cubic feet x 490 pounds/cubic foot).
1/2 cubic foot equals 864 cubic inches.
1 cubic yard = 27 cubic feet = 54 half-cubic-foot bags
0.5 is one-half, it takes 2 of these to make one cubic foot.
A cubic foot measures 12" x 12" x 12", so it contains 1728 cubic inches. Therefore, half a cubic foot is 1728/2, or 864 cubic inches. But the implication of the original question is PROBABLY meant to be -- what are the dimensions of a cube if its volume is one-half of a cubic foot? The exact answer, expressed in inches, is: (the cube root of 864) x (the cube root of 864) x (the cube root of 864); or, for practical purposes, just a little larger than 9.5" x 9.5" x 9.5".
60 pound of concrete bag makes 1/2 cubic foot of concrete
1,000 lbs or 454 Kilograms
Half a hundredweight is equal to 50 pounds. A hundredweight is a unit of weight equal to 100 pounds, so half of that would be 50 pounds.
1/2 cubic foot is 864 cubic inches.
