1 sq. feet = 144 sq. inches
392 sq. feet = 144 * 392 sq inches = 56448 sq. inches
Volume of cement needed = 56448 sq inches * 4 inch = 225792 cubic inches
225792 cubic inches = 1568 cubic feet
It depends upon how deep the cement will be.
depends how deep
I am building a curb that will be 26 feet long, 6.5 inches wide and 4 inches deep. How much cement do I need?
13*13*6=1014 yards of cement
26 square feet.
Convert the 4 inches into feet first. 4/12 = .33 feet. Now, compute the volume by multiplying the area of 64 square feet by .33 feet, and you get 21.12 cubic feet. Sometimes cement is ordered by the yard (cubic yard) and since there are 27 cubic feet in one cubic yard, you would divide 21.12 by 27 and get .78 yards.
well do to my calculations i made is that it is 6 or 18 feet long
The answer will depend on how deep the cement needs to be.
108 sq ft
One cubic yard covers 81 square feet 4 inches thick.
Any answer is possible.
800 square feet x 1/12 x 3/4 = 50 cubic feet.
4860 sq feet
2500 cubic feet.
You will need at least 9.68 cubic yards of cement.
4*8*1 = 32 square feet
800 C feet
147 cubic feet of cement are required.
About a ton.
answer-140 sq yds
Use this formula to convert from square inches to square feet, : square inches x 0.00694 = square feet
one yard of cement will make a 8 x 10 square foot slab at 4 inches thick, that's 80 sq. feet per yard of cement at 4 inches thick.
4.75 square feet
You can't convert that. You can convert feet to inches, or square feet to square inches.
To convert square inches to square feet, divide square inches by 144.
