How to Calculate Volume
Recognize a cube., Learn the formula for the volume of a cube., Find the length of one side of the cube., Plug the side length into the formula V = s3 and calculate., Be sure to state your answer in cubic units.
Step-by-Step Guide
-
Step 1: Recognize a cube.
A cube is a three-dimensional shape that has six identical square faces.In other words, it is a box shape with equal sides all around.
A 6-sided die is a good example of a cube you might find in your house.
Sugar cubes, and children's letter blocks are also usually cubes. -
Step 2: Learn the formula for the volume of a cube.
Since all of the side lengths of a cube are the same, the formula for the volume of a cube is really easy.
It is V = s3 where V stands for volume, and s is the length of the sides of the cube.
To find s3, simply multiply a by itself 3 times: s3 = s * s * s , Depending on your assignment, the cube will either be labeled with this information, or you may have to measure the side length with a ruler.
Remember that since it is a cube, all of the side lengths should be equal so it doesn't matter which one you measure.
If you are not 100% sure that your shape is a cube, measure each of the sides to determine if they are equal.
If they are not, you will need to use the method below for Calculating the Volume of a Rectangular Solid. , For example, if you find that the length of the sides of your cube is 5 inches, then you should write the formula out as follows:
V = (5 in)3. 5 in * 5 in * 5 in = 125 in3, the volume of our cube! , In the above example, the side length of our cube was measured in inches, so the volume was given in cubic inches.
If the side length of the cube had been 3 centimeters, for example, the volume would be V = (3 cm)3, or V = 27cm3. -
Step 3: Find the length of one side of the cube.
-
Step 4: Plug the side length into the formula V = s3 and calculate.
-
Step 5: Be sure to state your answer in cubic units.
