### How many yards in a ton?

As a rule of thumb, you can multiply the cubic yards by a factor of 1.4 to get tons. But remember, yards is a measure of volume where tons is a measure of weight. Thus, depending upon the material being calculated, true weight can vary greatly. Obviously a yard of wet sand will weigh far more than a yard of dry sand, as water is more dense and has more weight than the sand it displaces in the volume. Large crush stone may weigh far less than pea gravel for the same volume as there is less air gap around the gravel than there is around the large crush. If you need a true weight of a yard of some material, you would have to know its weight in a particular volume and then calculate from that value.

### What is cubic feet in 11 feet by 21 feet

You cannot calculate cubic feet from only two measurements. Cubic feet is an area of volume, such as the inside area of a box. With only two measurements you get square feet, which is a measurement of area. A box 11 feet by 21 feet takes up an area of 231 square feet (11 times 21). If the box is 3 feet tall, then you can compute cubic feet since you take all three values and multiply them together. A box 11 feet by 21 feet by 3 feet would contain 693 cubic feet of space (11 times 21 times 3).

### How many cubic yards would it take to fill in. 20' x 2' diameter

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

### How many cubic feet of soil do i need to cover 12x15x3x3 garden

you have to many numbers there
If you are saying 12'x15'x what deep 3 inches or 3' ?
12'x15'=180 sq ft x3' = 540 cubic feet or 20 cubic yards
x3inches= 40 cubic feet

### How many cubic yards is 3600 square feet in 6 inches?

1. Calculate
• Calculate your area (see below)
• Calculate your volume; Multiply area times the depth, this will be volume in cubic feet
• Calculate your cubic yards; Divide cubic feet by 27 to convert to cubic yards and this is your answer.
• Where (ft2) = square foot, (ft3) = cubic foot, (yd3) = cubic yard
3. or i'll do it 66 and 2/3 cu Yds

### How to calculate yards in a pile of gravel

A yard of material is 3x3x3 so that is 27 cubic feet. you have a pile that is 4x15x12 and that is 720 cubic feet. So divide 720 by 27 and you get 26.66 yards

### I don't know how to use my calculator on my dell desktop for calculating square yds. and feet

In the Windows calculator application located in the accessories folder in the start menu, you can calculate square yardage by using area formulas such as length times width for a rectangle/square. To enter this with a keyboard you would enter (the length)*(the height) as long as your units are in feet or yards you will get the answer in square feet or yards. The Windows 7/vista calculators have built in conversion factors for yards and feet that can be found by pressing view>unit conversion.
