While the US standard unit is a cubic yard or cubic inch, the more widely used units are gallons, pints, or fluid ounces. The following table shows a few units related to volume and its metric equivalents. Apart from this, large and small volumes are measured in other units like milliliter (ml), pints, gallons, and others. However, the most commonly used unit for volume is liter. unit of volume is cubic meter (m 3) since volume is a quantity of the three-dimensional space occupied by a shape or surface. Now that we are familiar with the formulas of various geometric shapes, let’s take a look at the different units of volume. The volume of a sphere whose radius r is 4/3 πr³. The volume of a sphere is the space occupied by it. The volume of a cone is calculated with the formula: 1/3 ×πr 2h. The difference between a cone and a pyramid is that the base of a cone is circular whereas the base of a pyramid is a polygon. This formula can also be written as 1/3 × Base area of the polygon × height of the pyramid. The volume of a pyramid is calculated with the help of the formula: Volume of a Pyramid = 1/3 × Base length × Base width × height of the pyramid. Pyramids have a polygon as their base and triangular faces that meet at the apex. If we consider 'r' as the radius of the circular base (and top) and 'h' as the height of the cylinder, then the volume of the cylinder can be expressed as Volume of a Cylinder = π r² h Volume of a Pyramid The distance between these two bases is the height of the cylinder. Just as we built up a cuboid using rectangles, we can build a cylinder using circles of the same size.Ī cylinder is a tube-like structure with two parallel circular bases which are joined by a curved surface at a fixed distance from the center. ![]() Observe the following figure to see the equal sides of a cube and the space it occupies. If we represent this equal value as ‘a’, then the volume of this cube can then be calculated with the formula: Volume of a Cube = a × a × a = a³. ![]() To calculate the amount of space enclosed by this cuboid, we use the formula: Volume of a Cuboid = l × b × h Volume of a CubeĪ cube is a special case of a cuboid where all three sides are equal in measure. This can be seen in the following figure which shows the length, width (breadth), and height of the cuboid thus formed. If we stack them one on top of the other up to height 'h', we get a cuboid of dimensions l, b, h. Suppose we have some rectangular sheets with length 'l' and width ' b'. Let us have a look at the volume of these solid shapes in detail. These real-life objects can be easily compared with the basic 3-D shapes. Then use it to estimate the volume lost to one indentation and multiply it by their number to get the actual chocolate filled volume.Every object in our surroundings has a nature of occupying space. One way to approach this curious problem is to first use the volume of a prism calculator above to calculate the volume of the bar, including the indentations. Many camping tents are also such prisms, making use of the same beneficial properties.Ī triangular prism volume calculation may also be handy if you want to estimate the volume of a toblerone bar. This type of roof has the best distribution of forces generated by the weight of the roofing and lateral forces (i.e. ![]() Practical applicationsĪ lot of classical roofs have the shape of a triangular prism, so calculating the volume of air below it might be useful if you are using the space as a living area. For example, if the height is 5 inches, the base 2 inches and the length 10 inches, what is the prism volume? To get the answer, multiply 5 x 2 x 10 and divide the result by 2, getting 10 x 10 / 2 = 100 / 2 = 50 cubic inches. ![]() Three measurements of a prism need to be known before the volume can be calculated using the equation above: the prism length, height, and base.
