What is 64 cubed?

• A. 262,1440
• B. 16384
• C. 2048
• D. 262,144

Answer: (D)

Cubing a number means multiplying it by itself three times. So for 64 cubed, compute 64 × 64 × 64. First find 64 × 64 = 4,096, then 4,096 × 64 = 262,144. Alternatively, since 64 = 2^6, (2^6)^3 = 2^18 = 262,144. The result is 262,144, which is the only option that matches.
