# Ultimate Guide to Understanding Cubic Feet

## Freight Density Calculator

### Logistics Cube Calculator or Cubic Feet Pallet Calculator

#### How to Calculate Freight Class?

To calculate cubic feet, start with determining the dimensions of a single pallet in your shipment. Eg: assume that you are shipping boxes that are sized at 3 ft x 4 ft x 5 ft.

Weigh the pallet. Assume that it weighs 260 lbs.

Calculate the pallet volume by multiplying the dimensions by each other.

For this case, 3 * 4 * 5 = 60 cu ft.

To calculate the density, divide the weight by the cargo volume: 260/60 = 4.33 lb/cu ft.

Compare this value with the table above to find the appropriate freight class.

In this case, your shipment belongs to freight class 200.

Now that you have the freight, take a closer look at it to optimize it. Read further for cost saving tips!

If your cargo density is just below the upper limit of the current freight class (for example, 7.98 lb/cu ft), adding just a small amount of weight from the pallet will bring higher class results and, subsequently, in lower freight rates. It is possible to have the opportunity to pay less in the end!

In addition, if the density is almost equal to the upper limit of the freight class, you could try reducing the volume by a few cubic inches by compacting your shipment a little more will bring in a more economic freight class.

**How many pallets fit in a trailer?**

The freight **LTL business** and the understanding **trailer cube **utilization is entirely about density.

When discussing 53 foot trailer cubic feet or 53′ trailer cbm. To determine how many pallets in 53′ trailer or the volume of a 53 foot trailer holds.

The equation is, 3816 cubic feet of air (8’ wide by 9′ high by 53′ long).

**How many pallets in a 53′ trailer?**

When understanding 53-foot trailer dimensions and weight.

Calculations show a 53-foot trailer (636” long) can hold 13 pallets lengthwise, with an extra 1 foot.

These wide trailers fit two rows of pallets. So loaded into every 53-foot trailer, the answer is is 26 pallets.

If we loaded air, 3816 cf would be a full load.

But we load a wide variety of shapes and sizes, some square, some rectangular, some round, with many pieces irregular in shape which create air pockets, no matter how well the trailer is loaded.

So we accept 64 cu. ft. (8’ x 8′) for each lineal foot of trailer as being the practical maximum loading.

Therefore, a load with 3400 cubic feet is about as perfect as anyone can get.

**The economics are based on the following expectations:**

48 foot trailer: 3000 cu. ft. or 30,000 lbs 53 foot trailer: 3400 cu. ft. or 34,000 lbs.

This explains the “conversion factor” of 10 lbs. per cubic foot.

This is called density and is very important in determining freight rates or charges when understanding pallet cubic feet.

**Cubic feet per pallet. **

Most office **furniture moves **on cube rates, so the density is not a big issue. However, some products are heavy with a little cube, so weight (density) is a factor, and we will charge on weight. Then there is warehousing to consider.

We treat each lineal foot of the trailer deck (floor) as equivalent to 64 cu. ft. (8′ x 8′ x 1’ = 64 cu. ft.) or 640 lbs.

This works out to 3392 cu. ft. for a trailer.

Sometimes skids are so irregular and awkward that nothing can be loaded on top, so the tariff has a rule for that.

When factories load head-loads, they cannot be touched, so rates are based on lineal feet used, and converted to weight or cube, as noted above.

This clear analysis will determine success or failure when understanding cubic feet specifically in the logistics service business.

**How many cubic feet are in a pallet?**

- “31.1 cubic feet”

To calculate pallet cubic feet. Multiply length 48″ x width 40″ x height 28″ (22″ plus 6″ of pallet) = 53,760 cubic inches.

Divide 53,760 by 1,728 = 31.1cubic feet.

Divide 110 pounds (80 lbs for the carton and approximately 30 lbs for the pallet) by 31.1 cubic feet = 3.54 pounds per cubic feet (PCF), i.e., density.
