Calculate 64 cubed.

Calculate 64 cubed.

• A. 128,000
• B. 64,000
• C. 262,1440
• D. 262,144

Answer: (D)

Cubing means multiplying a number by itself two more times. So 64 cubed is 64 × 64 × 64. First multiply 64 by 64 to get 4,096. Then multiply that by 64: 4,096 × 64 equals 262,144. You can also see this with exponents: 64 is 2^6, so (2^6)^3 = 2^18 = 262,144. Therefore, the result is 262,144. The other options aren’t the product of 64 × 64 × 64—one is too small, and one is exactly ten times too large.
