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).
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)
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).
An 80 lb bag of concrete typically yields about 0.6 cubic feet when mixed. Since there are 27 cubic feet in a cubic yard, half a cubic yard is 13.5 cubic feet. To find how many 80 lb bags are needed, divide 13.5 by 0.6, which equals approximately 22.5 bags. Therefore, you would need about 23 bags of 80 lb concrete to fill half a cubic yard.
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
