At 12 inch per foot that is 3.14x30x30*2/12/4 = 117.75 cubic feet of sand at 100 pounds per cubic foot = 11,775 pounds (5.88 tons). Since a yard is 27 cubic feet that is 117.75/27 = 4.4 yards
At 7.48 gallons per cubic foot that is 3.14x30x30/4x52 x7.48 /12 = 22,900 gallons
30ft² = 2.79m²
10 30/3=10
450
The answer will depend on the size of each cube.
fill it and find out ;)
30ft to 42ft 30ft to 42ft 30ft to 42ft 30ft to 42ft
30ft by 30ft
30ft 6inch = 929.64cm
15 cubic yards
8294400 ft4 which has no meaning.
No if he did fall off a 30ft cliff he wouldnt be where he is now.
30
A 30ft X 30ft roof would be 9 squares
At 7.48 gallons per cubic foot that is 3.14x30x30/4x52 x7.48 /12 = 22,900 gallons
A 30ft x 14ft room = 420 square feet.
30ft x 90ft = 2,700 sq ft or 250.8382 square meters.
