The space a three-dimensional object occupies

Volume is a measure of the amount of space that a three-dimensional object occupies. It is often expressed in units such as cubic meters (m), cubic feet (ft), or liters (L).

For example, if you have a box that measures 1 meter in length, 1 meter in width, and 1 meter in height, the volume of the box would be 1 cubic meter (1m). This means that the box can hold 1 cubic meter of material, which could be anything from air to water to a solid substance.

In the context of containers, the volume of a container refers to the amount of space that is available to hold a substance. For example, a water bottle with a volume of 500 milliliters (500 mL) can hold 500 milliliters of water.

The concept of volume is important in many fields, such as engineering, architecture, physics, and chemistry. For example, in engineering and architecture, volume calculations are used to determine how much material is needed to build structures such as buildings, bridges, and roads. In physics and chemistry, volume is used to describe the properties of gases and liquids, as well as to calculate the amount of a substance in a given sample.

Imperial volumes

  • 8 fluid drachms = 1 fluid ounce (fl oz)
  • 5 fluid ounce = 1 gill
  • 20 fluid ounce = 1 pint (pt)
  • 2 pints = 1 quart (qt)
  • 8 pints = 1 gallon (gal)
  • 2 gallons = 1 peck
  • 4 pecks = 1 bushel
