How to Calculate the Volume of a Cube
To calculate the volume of a cube with a side length
a, use the following formula:
In other words, multiply the side length of the cube by itself three times.
But what if the sides are not equally long? Then we are talking about a cuboid, not a cube.
How to Calculate Volume of a Cuboid
To calculate the volume of a cuboid, multiply the side lengths by one another using this formula:
c are lengths of the sides of the cube.
Find the volume of a cube with the side length
Solution. Let’s substitute the side length into the cube volume equation:
Answer. The volume of this cube is 8.
Find the volume of a cuboid with side lengths
Solution. Let’s substitute the side lengths into the cuboid volume equation:
Answer. The volume of this cuboid is
What is the side length of a cube with a volume of
Solution. To figure out the side length, you need to solve the variable
a in the cube volume equation.
To do this, take the 3rd root of both sides of the equation. This gives you:
Answer. The side length of a cube of volume 10 is approximately 2.15.
On a rainy day, a soccer field of size
110m x 80m gets
1cm of percipitation. How many liters of water is there on the field?
Solution. The water layer and the field form a cuboid. The height of the cuboid is 1cm. This needs to be converted to meters to get the right answer.
1cm = 0.01m. Now you can plug in the cuboids measurements into the cuboid volume equation.
Answer. The soccer pitch collected
88 000 liters of water on a rainy day.
