Hendecagon Weight

This Weight of a Hendecagon calculator computes the weight a column with a regular hendecagon face, a polygon with 11 equal sides of length (s) and a height (h) that has a mean density.   Regular Hendecagon Column

INSTRUCTONS: Choose units and enter the following:

• (s) Length of Hendecagon Sides
• (h) Height of Hendecagon Column
• (mD) Mean Density of Material

Mass of a Hendecagon Column (M): The mass / weight is returned in kilograms.  However volume can be automatically converted into compatible units via the pull-down menu.

The Math / Science

A regular hendecagon has eleven equal sides and equal angles.  The formula for the weight or mass of a hendecagon column is:

M = 11/4•cot(π/11)•s²•h⋅mD

where:

• M = mass of hendecagon column
• s - length of the side
• h - height of column
• mD = Mean Density of Material

• Volume of Hendecagon shaped column
• Weight of Hendecagon shaped column

Mean Density Table

Mean density is scientifically volume divided by mass.  There are  various unit for density adopted by cultures and industries. Common units for density included the following:

• kilograms per cubic meter (kg/m³)
• grams per cubic centimeter (g/cm³)
• grams per liter (g/L)
• pounds per cubic feet (lb/ft³)
• ounces per cubic inch (oz/in³)
• pounds per barrel (lb/bbl)
• pounds per bushel (lb/bu)

If you want to identify a material by its density, use the Density Within Range tool.

Weight is technically the downward force that a mass exerts based on the force of gravity and the mass of the object.  On the surface of the Earth, mass and weight are often interchanged.  In some places, objects are sold by the gram (mass), and in other locations, the same objects are sold by the ounce (weight).

The Weight Calculators use the dimensions of an object and its shape to compute the objects volume.  They then apply a density associated with a material to estimate the objects weight.
