Volume of any substance is usually the calculation of the amount of space a three-dimensional substance occupies. It is easier to calculate volume of solids as compared to the volume of liquids and gases. This article on how to calculate volume gives you tips on calculating volume of solids, liquids and gases.
- To calculate the volume of the gas we need to calculate the volume of fluid that is displaced by the gas.
- If you want to calculate volume of a liquid, then you need to pour the liquid in a container and calculate the space that is occupied by the liquid within the container.
- To calculate the volume of irregular shapes, you use the value of the liquid that is displaced by the solid.
- Volume of solids that have regular shapes can be calculated using formulae. These formulas will be helpful for you in calculating the volume of liquids as well as gases too, because liquids and gases take the shape of the container in which they are poured.
- You can identify the shape of the container and calculate the volume of the respective solids and liquids.
- You need to use a container of specific regular shapes and calculate the volume of liquids and gases. It becomes easier for you to calculate their volume easily using these containers.
- While calculating the volume of liquids, for the height, you need to measure the depth of the liquid within the container.
- Volume of any object is usually measured in cubic units i.e. cubic centimeter, cubic meter.
Some of the important formulae for calculating volumes of regular shapes are as given below:
- Formula for calculating volume of a cube is given as,
Volume of a cube = a3
In the above formula,
- “a” is the side of the cube.
- The formula for calculating volume of cone is given as,
Volume of a cone = (1/3) π r2 h
In the above formula,
- “π” is a constant whose value is 3.14 or 22
- “ r” is the radius of the base of the cone
- “h” is the height of the cone
- The formula for calculating volume of a cylinder is given as,
Volume of cylinder = π r2 h
In the above formula,
- “π” is a constant whose value is 22/7 or 3.14
- “r” is the radius of the base of the cylinder
- “h” is the height of the cylinder
- The formula for calculating volume of a sphere is given as,
Volume of sphere = (4/3) π r3
In the above formula,
- “π” is a constant whose value is 3.14 or 22/7
- “r” is the radius of the sphere
- The formula for calculating volume of a box is given as,
Volume of a box = l × b × h
In the above formula,
- “l” is the length of the box
- “b” is the breadth of the box
- “h” is the height of the box
- The formula for calculating volume of a rectangular prism is given as,
Volume of rectangular prism = l × w × h
In the above formula,
- “l” is the length of the prism
- “w” is the width of the prism
- “h” is the height of the prism
- The formula for calculating volume of a regular prism is given as,
Volume of a prism = b × h
In the above formula,
- “b” is the area of the base, usually base of a prism is triangular in shape. Therefore you can use the formula of area of a triangle (½ b × h) here.
- “ h” is the height of the prism
You can use the above formulae and calculate the volume of solids, liquids as well as gases.
