Answer» Correct Answer - Option 2 : 287496 Given: The given number = 66 Concept: Calculation skills trick Calculation: Step(1): Write down the cube of each of the digits in three digit format i.e. 6³ = 216 and 6³ = 216 The number obtained after this step is 216216. Step(2): Now multiply all the digit of the given number with themselves i.e. (6 × 6) = 36 Step(3): Multiply the result obtained in Step(2) by the power 3 i.e. (36 × 3) = 108 Step(4): Now multiply the result obtained in Step(3) with the given number i.e. (66 × 108) = 7128 Step(5): Add the number obtained in Step(1) with the number obtained in Step(4) keeping the unit place empty i.e. 2 1 6 2 1 6 _ 7 1 2 8 _ 2 8 7 4 9 6 ∴ Cube of 66 = 287496

Answer» Correct Answer - Option 2 : 287496

Given:

The given number = 66

Concept:

Calculation skills trick

Calculation:

Step(1):

Write down the cube of each of the digits in three digit format i.e. 6³ = 216 and 6³ = 216

The number obtained after this step is 216216.

Step(2):

Now multiply all the digit of the given number with themselves i.e. (6 × 6) = 36

Step(3):

Multiply the result obtained in Step(2) by the power 3 i.e. (36 × 3) = 108

Step(4):

Now multiply the result obtained in Step(3) with the given number i.e. (66 × 108) = 7128

Step(5):

Add the number obtained in Step(1) with the number obtained in Step(4) keeping the unit place empty i.e.

2 1 6 2 1 6

_ 7 1 2 8 _

2 8 7 4 9 6

∴ Cube of 66 = 287496
