find the cube of 216
Answers
Step-by-step explanation:
Steps to Solving the Problem
We know the word cube indicates three because of the shape of a cube. If we need to find the volume of a cube, we multiply the length times the width times the height. It is a three-dimensional object, so we need to multiply three measurements by each other to find the volume.
We can write out the cube root of 216 with a radical, like seen here:
Radical
So in our case, we need to figure out what number will multiply by itself three times to give us 216. In other words, we need to solve for x in the equation seen here:
x sqaured
x three times
Now to figure out what x is. The easiest way to do this is by plugging in different numbers for x to see what you get. Start with something small, like 2, to see what happens. If we plug in 2 for x and cube it, we get 8. . . that is way too small.
Let's jump up to 4 * 4 * 4 = 64. . . getting closer, but not there yet.
Now let's try five. 5 * 5 * 5 * = 125. Almost there!
6 * 6 * 6 = 216! Phew, we finally found out the answer. The cube root of 216 is 6. This means that each side of your box is 6 inches long. Now you can measure your closet to see if it will fit.
