![]() Where V is the volume of the cube and "a" is the length of one side of the cube. To calculate the volume of a cube, the following formula can be used: It's a regular polyhedron and a specific type of rectangular prism. In a cube, all edges are of equal length, and all angles between adjacent faces are right angles. Manual:Ī cube is a 3D shape that has six equal square faces, all of which are at right angles to each other. It is the distance from the centre of the base to the edge, and h is the height of the cone, which is the distance from the apex (top point) to the base. Where V denotes the volume of the cone, π is a mathematical constant equal to 3.14, and "r" is the radius of the circular base of the cone. Cones are typical of everyday objects like ice cream cones, party hats, and traffic cones. Click on the calculate button and get the resultĪ cone is a 3D geometric shape that has a circular base and a single vertex (apex) that is connected to the centre of the base by a curved surface.Enter the value of the radius in the respective field."r" is the radius of the sphere, which is the distance from the centre to the edge. You can usually use 3.14 as an approximation. "π" (pi) is a unique number, roughly 3.14159. "Volume" is the amount of space inside the sphere. To find the volume of a sphere manually, you can use a simple formula. The volume of the sphere is:Ī sphere is a perfectly round 3D shape, like a ball. It's a helpful tool for making sure you use your storage space effectively. This is handy when you're trying to pack things, ship items, or want to know how much space you have available. The volume calculator then does the math for you and gives you the answer, usually in units like cubic inches, cubic feet, or litres. Then, you enter the measurements of that shape, like its length, width, and height. To use it, you typically need to know the shape of the object, like whether it's a cube, a cylinder, or something else. It's like a virtual measuring tool that tells you how much stuff can fit into that space. Step 4. Set up the cancellation table so all units will cancel, except the desired unit, gallons.A volume calculator figures out how much space is inside a three-dimensional object, like a box or a container. Step 1. Use the equation for determining the volume of a cylinder. What is the capacity, in gallons, of the tank? The base of a cylinder is a circle, A = π × r 2, where π = 3.14.Įxample 3 - A cylindrical tank of foam concentrate is 5 feet tall. The volume of a cylinder is found by multiplying the area of the base times the height, h. The volume of the tank is 170 cubic feet or 1272 gallons. ![]() Step 5. Set up the cancellation table so all units will cancel, except the desired unit, gallons. Step 4. Set up the problem, and solve for volume. ![]() Step 3. Convert all the measurements to the same units, feet. Step 2. Identify the length, width, and height. What is the capacity of the water tank in cubic feet? In gallons? The volume of the tank of water is 240 cubic feet or 1,795 gallons.Įxample 2 - The water tank on a newly designed engine is 34 inches wide, 5 feet high, and 12 feet long. Step 5. Set up the cancellation table so all units will cancel except gallons (see Section 2.1). Step 4. Determine the appropriate conversion factor. Step 1. Use the equation for determining the volume of a rectangle. The volume of a rectangular container is determined by multiplying the length (l) by the width (w) by the height (h).Įxample 1 - Determine the volume of the tank in gallons. It is used by firefighters to answer questions like "How much water is left in the tank?" and "At 15 gallons per minute (gpm), how many more minutes before the tank is empty?" ![]() Volume is used to indicate the capacity of a tank or container.
