Sonotube Volume Calculator

Formula

The formula to calculate the volume of a Sonotube is:

\[ V = \pi r^2 h \]

Where:

\( V \) is the volume of the Sonotube
\( r \) is the radius of the Sonotube
\( h \) is the height of the Sonotube
\( \pi \) is a mathematical constant whose approximate value is 3.14159

What is a Sonotube?

A Sonotube is a brand name for a type of cardboard tube that is commonly used in construction projects. These tubes are typically filled with concrete to create cylindrical columns that can be used as the foundation for structures like decks, lamp posts, and buildings. They are designed to be strong and durable, yet easy to remove once the concrete has hardened. Sonotubes come in a variety of sizes to accommodate different project needs.

Example Calculation

Let's assume the following values:

Radius of the Sonotube (r): 2 units
Height of the Sonotube (h): 5 units

Step 1: Calculate the Volume (V):

\[ V = \pi r^2 h = 3.14159 \times 2^2 \times 5 = 3.14159 \times 4 \times 5 = 62.8318 \text{ cubic units} \]

The volume of the Sonotube is 62.8318 cubic units.
