Equation to find volume
What are the two formulas for volume?
The answers have one, two, or three dimensions; perimeter is measured in linear units , area is measured in square units , and volume is measured in cubic units .Perimeter, Area, and Volume.

|---|---|---|
| Shape | Formula | Variables |
| Right Rectangular Prism | V=LWH | L is the length, W is the width and H is the height. |
What are the 3 ways to find volume?
Different Ways to Find VolumeSolve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions. Solve for Volume by Density and Mass. Density is defined as an object’s mass per a given unit of volume. Solve for Volume by Displacement.
How do you find volume example?
In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.
What is the formula for volume of liquid?
You weigh the cannonball and find it weighs 20 lbs. You now have enough information to calculate its volume, so just rearrange the density formula to solve for V: V = m/ρ.
What is the volume of this cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .
How do you calculate volume of a tank?
See the formulas below and select the one for your style.Cylinder Tank Formula. tank volume = π × r2 × l. r = radius (diameter ÷ 2) Oval Tank Formula. area = ((h – w) × w) + (π × r2) tank volume = area × l. Capsule Tank Formula. cylinder volume = π × r2 × l. Rectangular Tank Formula. tank volume = l × w × h.
How do you calculate volume in Litres?
The first thing you need to do is multiply the length by the width by the height. That gives the number of cubic millimetres. To calculate the number of litres, you then divide that number by a million. As an example, let’s take a box measuring 406 x 356 x 203mm.
What unit is volume measured in?
The SI unit of volume is the cubic meter (m 3 ), which is the volume occupied by a cube that measures 1 m on each side. This very large volume is not very convenient for typical use in a chemistry laboratory. A liter (L) is the volume of a cube that measures 10 cm (1 dm) on each side.
How do you find the volume of all shapes?
The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space.Volume Formulas of Various Geometric Figures.
| Shapes | Volume Formula | Variables |
|---|---|---|
| Rectangular Solid or Cuboid | V = l × w × h | l = Length w = Width h = Height |
What is the volume of a shape?
Volume is the amount of space a 3D shape takes up. You can work out the volume of a shape by multiplying height × width × depth. If the shape is made of cubic cm blocks, you can count the cubes to find the shape’s volume.
What is the formula for volume of hollow cylinder?
Volume of Hollow Cylinder Suppose, r1 and r2 are the two radii of the given hollow cylinder with ‘h’ as the height, then the volume of this cylinder can be written as; V = πh(r12 – r22)
