HOW DO i CONVERT 42" X 30" X 12" TO CUBIC FEET

cubic capacity is pye X radius squared X depth
that is 3.1416 X 5.33 squared by 1 .3 ft
that is 3.1416 X 28.408 X 1.3
that is 118.69 cubic ft
1 cubic ft = .0370 cubic yards
multiply 118.69 cubic ft =4.39c yards or you can convert the feet to yards first and then apply the formula
so that is 3.1416 X 1.77 squared =
3.1416 X 3.13= 9.83 sq yards X .43 yards =4.22 cubic yards
the difference is from how many decimal points you go to
for each number

You can't convert cubic feet to square feet because cubic feet has an extra dimension, you could fit an unlimited number of square feet into cubic feet.

The formula for Cubic feet is:
length × width × height

The formula for Square feet is:
length × width

How it Works

Stone and Mulch Calculators

As an example, let's use 500 square feet to be mulched at a
3" depth.

1. First, the depth must be converted to feet. To convert inches to feet, simply divide inches by 12, the number of inches in a foot.
   
   So for our example: 3 inches divided by 12 equals a 0.25 foot depth.
2. Now that we have the depth in feet, we can multiply the depth by the area.
   
   So for our example: 0.25 foot depth times 500 square feet equals 125 cubic feet.
3. If you are calculating 0.5, 2, or 3, cubic foot bags, simply divide 125 cubic feet by the size of the bag.
   
   So for our example: if we are using 2 cubic foot bags, we can divide 125 cubic feet by 2 which equals 62.5 bags.
4. If you are calculating cubic yards, we need to convert 125 cubic feet to cubic yards by dividing by 27. One cubic yard is equal to 27 cubic feet, see the diagram below.
   
   
   
   So for our example: 125 cubic feet divided by 27 equals 4.63 cubic yards.

For Your Information

• 1 inch equals 0.08333 feet
• 1.5 inches equals 0.125 feet
• 2 inc

We need to convert everything to a common unit, so let's convert the 18 inches into 1.5 feet.
Volume is length times width times height.
v= 132 x 2 x 1.5
v= 396 cubic feet
To convert to cubic yards, imagine a yard cube. It is 3 feet by 3 feet by 3 feet for a total of 27 cubic feet.
v1 = 396 cubic feet/27 cubic feet per yard
v1 = 14 2/3 cubic yards

So 15 cubic yards should do it.

Good luck.

First step - convert everything to feet - 5" is 5/12 of a foot

40 x 4 x 5/12 = 66.6 cubic feet.

Since a cubic yard is 3 feet by 3 feet by 3 feet, there are 27 cubic feet in a cubic yard.

66.6 cubic feet / 27 cubic feet/cubic yard = 2.5 cubic yards.

Good luck.

Square feet is calculated L x W so 10x10 would be 100 sq. feet, Cubic feet is calculated by L x W x H so 15 x 14 x 9 = 1890 cubic feet

17.6 cubic feet is 17.6 cubic feet.

You can't convert cubic feet to feet any more than you can convert your height to gallons.

Inch is a measure of length and cubic feet is a measure of volume. There is no conversion between them. It's just like trying to convert inches to gallons, it can't be done.

Now if you want to convert cubic inches to cubic feet, that's possible. Since there are 12 inches to a foot, there are 12-cubed or 1728 cubic inches in a cubic foot.

That is something that cannot be done (cubic to square). You can convert cubic meters to cubic feet or square meters to square feet as follows:

Multiply cubic meters by 35.3146 to get cubic feet

Multiply square meters by 10.7639 to get square feet
