Using density of steel @ 490.06 pounds per cubic foot (approx)
8 * 10 * (1/12) * 490.06 = 3267.07 pounds (approx)
It would weigh about 14.3 pounds .
Gypsum or plaster board3 3/8 inch 1.56 pounds per square foot 1/2 inch 2.08 pounds per square foot 5/8 inch 2.60 pounds per square foot
it comes in several weights per foot but most common is 5.4#/ft.
using info fromHow_does_one_cubic_foot_of_steel_weighyou'll get 1,304 lbs.
There 12 inches to a foot, so 120 tenths of an inch to a foot.
Steel is typically 490 lb/cubic foot. There are 1,728 square inches in a cubic foot which means that each cubic inch weighs about .284 pounds (just a bit over a quarter of a pound per square inch).
The density of steel alloy varies depending on its constituents and ranges between 7,750 and 8,050 kg/cu mtr (4.48 and 4.65 oz/cu in).It will therefore weigh between 645.12 and 669.6 ounces.
Got a calculator? Multiply 4 X 12 X 8 X 12 X 0.5 X 0.283 answer is pounds (lbs) LINK: http://wiki.answers.com/Q/What_is_the_density_of_low_grade_steel
TO answer this question, you need to know the density and the volume of the piece of steel. For example, "mild steel" weighs .284 pounds per cubic inch. The volume of a 12 inch x 12 inch x 1 inch piece of steel is 12 * 12 * 1 = 144 cubic inches. .284 pounds/inch^3 * 144 inch^3 = 40.896 pounds. So each of these steel tiles will weigh about 41 pounds.
The density of steel varies based on the alloying constituents but usually ranges between 484 and 503 lb/cu ft. The volume described in the question is (1.5" x 32" x 32") = 1,536 cubic inches = 8/9 cubic foot. So, depending on the steel mix, it weighs between 430.2 and 447.1 pounds.
If you mean a container with a volume of 1 cubic foot, then: 1/4 inch ball = 0.0082 cu. inch weigh of each ball (steel) = 0.0023 pounds approx. 73.6 balls per cubic inch (allowing for spherical interlocking) 1728 cubic inches ( one cubic foot) x 73.6 x 0.0023 = 292 pounds. So a cu. ft. container will hold close to 300 pounds of quarter inch steel balls.
It is not possible to blast a hole in 2 inch steel plate with a 12 gauge slug. The slug will barely dent the plate, if it does anything at all.

It depends on the type of steel
0.283 lb. per cubic inch
It depends on the length and width of the plate, and the thickness. A 12 x 12 inch piece of plate aluminum which is 1/2 inch thick has the same length and width as a 12 x 12 inch piece which is 1/4 inch thick, but the 1/2 inch piece will weigh twice as much.
