Understanding Volume
Volume measures the amount of three-dimensional space an object occupies. For a Cube, all sides are equal, so we multiply the side length by itself three times. For a Cylinder, we calculate the area of the circular base and multiply it by the height. For a Sphere, the volume depends entirely on its radius. This tool provides precise spatial measurements for all three types.
Frequently Asked Questions
What are the formulas? +
- Cube: $V = a^3$
- Cylinder: $V = \pi r^2 h$
- Sphere: $V = \frac{4}{3} \pi r^3$
- Cylinder: $V = \pi r^2 h$
- Sphere: $V = \frac{4}{3} \pi r^3$
What units are the results in? +
Volume is always measured in "cubic" units. If your inputs are in centimeters, your result is in $cm^3$. If in meters, your result is in $m^3$.
Does this handle liquid volume? +
While this tool calculates geometric volume, you can easily convert the result to liquid units. For example, $1,000$ cubic centimeters ($cm^3$) is exactly equal to $1$ Liter.
What is the radius of a sphere? +
The radius is the distance from the center of the sphere to any point on its surface. It is exactly half of the diameter.
