4.2 cubic ft.equals how many inches - Office Equipment & Supplies

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

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

2.33 Cubic Yards

Hi Bob:
1 cubic yard is 3ft by 3 ft by 3 ft.
3 times 3 times 3 equals 27, so
1 cubic yard equals 27 cubic feet.
2 1/2 inches divided by 12 inches equals .2083333 feet
196 square feet times .208333 feet equals 40.83333 cubic feet
40.83333 cubic ft divided by 27 cubic ft equals 1.5123456 cu yards.
Ta Da!!!!

Do you mean how many cubic yards it would require to fill a volume occupied by an area of 30 ft by 40 ft by 4 ins deep? If this is what you mean then it would require 11.1 cubic yards. Hope this helps.Sorry I can't help with the cost.

1.1 (cubic feet) = 1 900.8 cubic inches - that is length x depth x height... could be 1 inch by 1 inch by 1900 inches high (unlikely)... but that would still be 1.1 cu ft... or 12 inches by 12 inches by 13.2 inches... and so on

1 Cubic Foot = 29.9220779 Quarts [Fluid, US]
1 Cubic Foot = 25.71404638 Quarts [Dry, US]
1 Quart [Fluid, US] = 0.0334201389 Cubic Feet
1 Quart [Dry, US] = 0.0388892508 Cubic Feet

So roughly about 2.1 Cubic feet

You need three dimensions for a volume.
30 inches by 25 inches is 750 square inches or about 5.21 square feet.

If you want to calculate the volume of an object and have the answer in cubic feet.

Volume=Length X Width X Height
With the dimensions you give
Volume=12.5in X 37in X 20in
Volume=9250 cubic inches

To convert 9250 cubic inches into cubic feet you need to understand that there are 1728 cubic inches in 1 cubic foot.
L X W X H = 12"X12"X12"=1728 cu in

You then multiply 9250cu in and (1/1728cu ft) Really you are dividing 9250 by 1728.
your answer is 5.35 cubic feet.

12 inches in 1 foot
144 square inches in 1 square foot
1728 cubic inches in 1 cubic foot

to convert you put the unit you want to keep on top of the dividend.
to conver to to feet ( randomly selecting 100 inches)
Example converting 100 inches to feet

100inches X ____1ft____ = (100/12) = 8.3 feet
12inches

or cubic inches to cubic feet
4000 cubic inches to cubic feet

4000cu in X ____1cu ft____ = ( 2.33 cu ft)
1728 cu in

if you notice that the units on top and bottom of the dividend cancel each other out leaving the numerator (top number) as your unit.
it also works in reverse

2.33 cu ft X ___1728 cu in____ = (4000 cu in)
1cu ft
