Approximately 1,775.9 pounds.
7.5 cubic feet = 0.27 cubic yards.
How do you get volume in cubic feet from from a height of 5.5 feet in a half circleThe answer depends on whether the shape is a hemisphere or a cylinder cut in half along its axis.
First, determine the number of cubic feet. Pipe is 4 feet in diameter- so radius is half that- 2 feet. Area is pi (3.14) times radius squared. 2x2=4, x 3.14 = 12.56 SQUARE feet of area. Multiply that by the length in feet- 5,280, and you get a VOLUME of 66,316.8 CUBIC feet. one cubic foot holds 7.48 gallons- so your pipe can hold 496,084.115 gallons of water- almost a half million gallons.
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).
It is slightly bigger that the space occupied by a box 4 feet long by 4 feet wide by 4 feet high or a large wardrobe (7 and half feet by 4 and half feet by 2 feet).
1 UK gallon of water weighs 10 lb 1 cubic foot of water contains 6 1/4 gallons (6.25) and so weighs 62.5 lb so 54 cu feet weigh 54 X 62.5 lb or 3375 lb (or just over 1 and a half tons)
A cubic metre (or 'stere' as it is correctly known ) is 35.1 cubic feet. -In wet asphalt concrete that weighs about 5,250 pounds - just over 2 and a half tons !
1 gallon = 231 cubic inches1 cubic foot = 1,728 cubic inches1 acre = 43,560 square feet1/2 inch = 1/24th footWater volume = (43,560 / 24) cubic feet = [ 43,560 x 1,728 / (24 x 231) ] = 13,577 gallons (rounded)
You have three dimensions here 5.5 x 5 x 1.5 which means you are looking for cubic feet. The answer is 41.25 cubic feet.
3.5 cubic feet = about 26.18 US liquid gallons or 22.5 US dry gallons.
1 cubic yard = 27 cubic feet = 54 half-cubic-foot bags
the volume =pi (3.14) x your radius (half of your diameter) squared x height =volume. your answer is 753.8 cubic feet
