6th Grade Math : How to Calculate the Rank of Three or Cubic Numbers

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 "n3.", 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 S3. Thus, the volume of the cube above = 43 or 4 x 4 x 4 = 64.
Because the cubic, then the unit becomes 64 cm3.

As your study materials, please memorize the rank of three 1-10 below!
13 = 1 x 1 x 1 = 1
13 = 2 x 2 x 2 = 8
13 = 3 x 3 x 3 = 27
13 = 4 x 4 x 4 = 64
13 = 5 x 5 x 5 = 125
13 = 6 x 6 x 6 = 216
13 = 7 x 7 x 7 = 343
13 = 8 x 8 x 8 = 512
13 = 9 x 9 x 9 = 729
13 = 10 x 10 x 10 = 1,000

Example 2:
Results from 63 + 53 are ...
Discussion:
63 = 216
53 = 125
216 + 125 = 341
Thus, the result of 63 + 53 is 341.

Well, now please try to do yourself some of the problems below!

1. The result of 253 is ...
Answer: ............ ..
