How Many Feet In A Cubic Foot? Ordering Enough Material

When it comes to taking care of your own property, you might have to purchase different filler materials depending on what the problem is or what projects you want to do. For example, if you are looking to repair holes or make the ground even, you might want to order a few cubic feet of fill dirt.

But if you want to repair gardens or do landscaping, you might want to order top soil or mulch instead. Knowing how much material to order can be very hard, but by taking the proper measurements and calculations, you can actually figure out how much you will need.

How Many Feet In A Cubic Foot - Is There A Straight Answer?

A cubic foot denotes volume instead of just indicating a certain area. Since a cubic foot measures the length, the width and the height, this unit of measurement is talking about a three dimensional object. A foot on the other hand refers to length and it only talks about a one dimensional object.

With that said, you cannot actually calculate how many feet there are in one cubic foot simply because a cubic foot has 2 extra dimensions that a 1 foot in length does not have. It is simply not possible for one to know how many feet there is inside a cubic foot.

As a matter of fact, since a foot is an object that is made up only of a single dimension, you can actually fill 1 cubic foot with an endless number of 1-foot lengths. That is how complicated this question is especially when viewed at a mathematical standpoint.

Is There A Practical Or Realistic Answer?

In most cases, people end up asking this question simply because they want to know how much material they will need to fill holes, cover lawns or to do construction projects. What typically happens is that they want to know how much volume is needed by measuring only the length.

For example, they have a hole in their lawn that is 8 feet long and they want to know how many cubic feet of fill dirt do they need to order to fill it up. Another example would be if they have a play area that is 10 feet long and they want to know how many cubic feet of mulch would they need to cover it.

If this is the case, you actually have a realistic question rather than one that tackles about mathematical limitations. To answer your question, you will need to have a practical solution. This can only be done by gathering more data specifically with regards to the actual area and the desired depth.

You see, 8 feet long and 10 feet long does not talk about area or depth, it only talks about length. You can get the area by measuring the length as well as the width of the hole, or of the playground. As for the depth, it will depend on your need or preferences. If you need to fill a hole, measure how deep it is.

Solving The Problem

Now that you have the necessary data, you will then have to multiply its length by the width so that you will be able to get the area in square feet. You should then check how deep the area needs to be filled in inches. If you are looking to add a layer of mulch, then I suggest that you use only a 1-inch layer on top.

But if you need to fill a hole with material, you should try to measure how deep it is in inches. For example, if you need fill dirt for your lawn that measures 8 feet long by 8 feet wide by 3 inches deep, you can calculate how many cubic feet of material you will need to order by doing the following:

Multiply the length with the width 8 x 8 = 64 square feet. Convert the inches into feet by dividing the depth in inches by 12. So 3 inches divided by 12 is 0.25 feet. To determine how many cubic feet I will need to order, I will have to multiply the area by the depth. So 64 sq. ft. X 0.25 ft. = 16 cubic feet.

This simply means that in order for me to fill the area properly, I will have to order 16 cubic feet of fill dirt to cover an area in my property that is 8 feet long, 8 feet wide and 3 inches deep. By supplying all the data and calculating, you will know precisely how much material you will need to order.


It is actually impossible to know how many feet there is in one cubic foot. This is because feet is just a measurement of length, while a cubic foot measures volume. You cannot convert one to the other and there is actually an endless number of 1- foot lengths in one cubic foot.

Since it cannot be solved, you will have to understand the nature of the question. In most instances, it is asked to determine how much material one needs to fill or cover a certain length in his or her property. If that is the case, you will need to follow the calculations so you will know how much material to order.
