Measure this distance using appropriate units (e.g., inches or centimeters). In other words, it is how “tall” or “long” your prism is. The height (or length) of a prism is defined as the perpendicular distance between its two parallel bases. Step 3: Determine the height of the prism Make sure to use consistent units when performing calculations. – Other polygons (such as hexagons): Divide the polygon into triangles and find the sum of their areas. Each shape has its own formula for finding the area: Once you’ve identified the base’s shape, calculate its area. Is it a triangle, a rectangle, or perhaps another polygon? This article will guide you through the process of calculating the volume of a prism.īefore diving into calculations, examine the prism carefully to determine its base shape. Regardless of the shape, calculating the volume of a prism follows a straightforward formula. Prisms can come in various shapes with different base polygons, such as triangular, rectangular, or even hexagonal prisms. Through the diameter the surface area of the base can be calculated and then to get the volume just multiply it by the cylinder's height.In geometry, a prism is a three-dimensional figure with two congruent and parallel polygonal faces called bases and lateral faces made up of rectangles or parallelograms. Our volume calculator requires that you insert the diameter of the base. In many school formulas the radius is given instead, but in real-world situations it is much easier to measure the diameter instead of trying to pinpoint the midpoint of the circular base so you can measure the radius. You need two measurements: the height of the cylinder and the diameter of its base. The volume formula for a cylinder is height x π x (diameter / 2) 2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius 2. To calculate the volume of a tank of a different shape, use our volume of a tank calculator. By designating one dimension as the rectangular prism's depth or height, the multiplication of the other two gives us the surface area which then needs to be multiplied by the depth / height to get the volume. They are usually easy to measure due to the regularity of the shape. To calculate the volume of a box or rectangular tank you need three dimensions: width, length, and height. To find the volume of a rectangular box use the formula height x width x length, as seen in the figure below: For this type of figure one barely needs a calculator to do the math. It is the same as multiplying the surface area of one side by the depth of the cube. The only required information is the side, then you take its cube and you have found the cube's volume. The volume formula for a cube is side 3, as seen in the figure below: air conditioning calculations), swimming pool management, and more. Volume calculations are useful in a lot of sciences, in construction work and planning, in cargo shipping, in climate control (e.g. The result is always in cubic units: cubic centimeters, cubic inches, cubic meters, cubic feet, cubic yards, etc. All measures need to be in the same unit. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above.
