**How to Calculate the Rank of Three or Cubic Numbers**: The power of three or cubic number is multiplication three times with the same number. The symbol of the power of three or cubic numbers is "n

^{3}.", meaning n x n x n. Typically, the power of three is used to find the volume of a cube that has been known either side or rib length.

*Example Problem 1:*

A cube has a side length of 3 cm. What
is the volume of the cube?

*Answer:*

To find the volume of the cube above
that is by using the power of three. Because, basically the formula for finding
the volume of the cube is the side x side x side or S

^{3}. Thus, the volume of the cube above = 4^{3}or 4 x 4 x 4 = 64.
Because the cubic, then the unit becomes 64 cm

^{3}.
As your study materials, please memorize
the rank of three 1-10 below!

**1**

^{3}= 1 x 1 x 1 = 1**1**

^{3}= 2 x 2 x 2 = 8**1**

^{3}= 3 x 3 x 3 = 27**1**

^{3}= 4 x 4 x 4 = 64**1**

^{3}= 5 x 5 x 5 = 125**1**

^{3}= 6 x 6 x 6 = 216**1**

^{3}= 7 x 7 x 7 = 343**1**

^{3}= 8 x 8 x 8 = 512**1**

^{3}= 9 x 9 x 9 = 729**1**

^{3}= 10 x 10 x 10 = 1,000*Example 2:*

Results from 6

^{3}+ 5^{3}are ...
Discussion:

6

^{3}= 216
5

^{3}= 125
216 + 125 = 341

Thus, the result of 6

^{3}+ 5^{3}is 341.
Well, now please try to do yourself some
of the problems below!
