How much premixed cement needed to fill 1 cubic foot

Wait wait.

Do you mean a 25 SQUARE foot flower bed. You do say flower bed "area".

If so the answer is different. 1 cubic yard is 27 cubic feet. So, just one cubic yard will cover 27 SQUARE feet to a depth of 1 foot. (27 x 1 = 27).

I'd say on that basis you need 1/2 cubic yard. The wisdom I've seen says to cover soil with about 4" of mulch.

Hi Paula:
A mathematical logic question.
You need to get all of the measurements in the same units.
- A cubic yard is 1 yard x 1 yard x 1 yard
- equals 3 ft x 3 ft x 3 ft
- equals 27 cubic feet,
so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.
- Volume of a cylinder (the pipe) is the cross sectional area X length.
- Area equals Pi x r squared.
- equals 22/7 x 1 x 1
equals 3.14#####
times length (20)
equals 62.857### cubic feet volume
divide by 27 cubic feet
equals 2.328### cubic yards.

- The answer is always the easy part.
- what is important is knowing exactly what the question is, and
- determing what calculations are needed to get the answer.

Wasn't that better than if I'd just said 2 1/3 cubic yards?
Cheers

A cubic foot is a measure of volume that is 1 foot by 1 foot by 1 foot.
There are 12 inches in a foot, so there are 12 x 12 x 12 cubic inches in a cubic foot.

If you have a more specific question, let me know.

Good luck.

A cubic foot is one foot by one foot by one foot or 1' length by 1' width by 1' depth.

We multiply the figures to get the number of cubic feet, since they are all assumed to be in feet and get 600 cubic feet.

Good luck.

Hi Debbie:
You still get to use your calculator, but you need to use the mathematical formulae dealing with circles.
Area = pi times r squared
Volume of a cylinder = Area (of one end) times length.

For your cement mixer, (Average the diameter for simplicity)
All of the measurements need to be in the same units, lets use inches, then convert it to cubic feet.....
the volume would be:
pi (22 divided by 7)
times
1/2 diameter
times
1/2 diameter
times
depth

For my ancient mixer that would be:
22 / 7 x 10" x 10" x 22" = 6,914 cubic inches
1 cubic foot equals 12" x 12" x 12" equals 1728 cubic inches.
6,914 divided by 1728 equals 4 cubic feet.

Now we don't fill it right up, but that is its capacity.

Hope that helps.
By the way, my mixer likes 10 shovel fulls of navvy, 2 shovels of type 10 cement, and about 2 quarts of water to get a nice mix.
I do the water first,
then 5 navvy
then 2 cement
then another 5 navvy,
then just enough water to get the right consistency.
Cheerfuls!

1 cubic foot = 7.48051948 US gallons
1 cubic foot = 6.22883545 Imperial gallons

These are not the same, so cannot be directly converted.

Pounds per sq ft is a measure of pressure, while lbs / cu ft is a measure of density, weight per unit volume.

I think maybe what you are doing here is converting the weight of concrete in a 1" slab, where a sq ft would contain

1 x 1 x 1/12 = .0833 cu ft

The figure of 150 lb/ cu ft is correct for the average density of concrete, so the above slab would have

1/12 x 150 = 12.5 lbs/sq ft at 1" thickness

BTW that is a thin slab of concrete, insufficient even for a light-duty pathway. If you are referring to a screed for tiling or similar, that is cement.

3 feet x3 feet x3 feet = 27 cubic feet in cubic yard

1 bag concrete mix is 2/3 cu feet or .66 cu feet
41 bags cement mix will make 1 cubic yard

To get cubic feet, you multiply the length of each of the three sides.
So:

If something is 1 foot by 1 foot by 1 foot, that's 1x1x1=1 cubic feet
If it's 1 foot x 2 feet x 3 feet, that's 1x2x3=6 cubic feet
and so on...

kakima is 100% correct, but to add to it so you understand how he got that 27 cubic feet... you can picture a cube.
A cubic yard is 3 foot tall x 3 foot wide x 3 foot high.
(A cubic foot is 1 foot tall x 1 foot wide x 1 foot high).

So 3 x 3 x 3 = 27.
