Gallons x 0.133681 = cubic feet
25 cubic yards is 675 cubic feet.
You cannot convert square feet into cubic meters..the dimension don't match. the one is to the power of 2 and the other to the power of 3. if you mean convert 25 ft2 into meters squared. then 1 ft = 0.3048 m thus 1 ft2 = 0.092903 m2 Thus 25 ft2 = 2.32258 m2
(25 cubic feet) - (20.7 cubic feet) = 4.3 cubic feet
25 gallons is 3.34 cubic feet.
25 US gallons = about 3.34 (3.34201389) cubic feet.
First, calculate the volume of the pool in cubic feet (15 x 25 x 3) = 1125 cubic feet. Then convert cubic feet to gallons. Since 1 cubic foot contains 7.48 US gallons, multiply 1125 cubic feet (1125 x 7.48) to arrive at the result, 8415 US gallons.
25 US gallons is 3.342 cubic feet.
That depends on the depth of the topsoil you will put down. Multiply the number of square feet by the depth of topsoil--that will give you the number of cubic feet. To convert to cubic yards, divide the number by 27. So, for example, if you are using 3" of topsoil over 880 square feet then your calculation would be: 880 times .25 (3" = .25 feet) = 220 cubic feet (divided by 27--there are 27 cubic feet in a yard) equals 8.15 cubic yards.
Cannot be done without knowing the composition (most importantly the density) of the sand
25 feet x 50 feet x 4 inches = 416.25 cubic feet
25 US gallons equals 3.342 cubic feet.
