## Rectangular Hollow Tube Weight Formula

The following formula is used to calculate the weight of a Rectangular Hollow Tube.

W = (H*W – (W-t * H-t))*L*D

- Where W is the Rectangular Hollow Tube Weight (lbs)
- H is the height of the tube (in)
- W is the width of the tube (in)
- t is the thickness of the tube wall (in)
- L is the length of the tube (ft)
- D is the density of the tube (lbs/ft^3)

To calculate the weight of a hollow rectangular tube, subtract the inner volume from the total volume, then multiply the result by the density.

## What is the weight of a Rectangular Hollow Tube?

The weight of a hollowed-out tube is equal to the total weight of the rectangular tube minus the weight of the inside hollow portion of the tube (if it would be solid).

## How to calculate Rectangular Hollow Tube Weight?

Example Problem:

The following example outlines how to calculate the Rectangular Hollow Tube Weight.

First, determine the width of the tube. In this case, the width is 5 inches.

Next, determine the height of the tube. For this example, the height is measured to be 3 inches.

Next, determine the wall thickness. This is measured to be .50 inches.

Next, determine the length of the tube. The length is measured to be 10 ft.

Next, determine the density of the material the tube is made from. This tube has a density of 500lbs/ft^3.

Finally, calculate the Rectangular Hollow Tube Weight using the formula above:

W = (H*W – (W-t * H-t))*L*D

W = (((5/12*(3/12))- ((5/12-.5/12) * (3/12-.5/12)))*10*500

W = 1562.5
