# Yards in a pile of gravel

What is an easy way to calculate square yards in a pile of gravel that is 4' high, 15' length and 12' wide? The person I bought it from said it was around 15 to 17 yards. Would that be correct?

There are 27 cubic feet in one yard. IF your estimate of pile size is correct, you have 720 cubic feet witch is 26 yards.

Brad Bs. answer is correct if you said it was in a cube. But you said pile. So we need to make some assumptions. Like the angle of the pile. Lets make it easy & guess about 45 degree slump.
4' high = 1.33 yd X 15' long = 5 yd. X 12' wide = 4 yd.
So 1.3 yd. x 5 yd. x 4 yd. = 26.6 cubic yards. But with a 45 degree slump at lest 1/2 of this cube is air so you most likely have about 13 cubic yards of gravel. If your slump is more like 30 degrees you will have even less gravel. And I didn't subtract for the slump on both ends so I doubt you have more than 10 cubic yards in your pile. sorry.

### Formula to calculate square feet from feet

Measure the length and the width and multiply the two together. So if your bedroom is 15 feet long and 12 feet wide it would be 180 square feet.

If you wanted it in yards, you would divide by 9 so 20 square yards.

If you want to be really accurate you can go as close as 3 inches
3" would be .25
6"would be .5
9" would be .75

so if it was 15 foot 6" x 12 foot 3", you would multiply 15.5 x 12.25.

### Need to fill a 132ft long ditch that is 2 ft wide and 18in high with rock. how many yards do I need

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.

### 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 do I calculate square feet of a room for wallpaper

Measure the length and width of each wall, and then add up the resulting answers. So, if a wall is 9' tall and 12' wide, it is 108 sq feet. If another wall is 9' tall and 11' wide, it is 99 square feet. Your total would now be 99 + 108 or 207 square feet.

If you are doing it in feet and inches, you have to covert the inches to feet by dividing them by 12, since there are 12' in a foot. So with 3", divide 3 by 12 and get 0.25.

### 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.
