What is 7 cubed?

To find the value of 7 cubed, you raise 7 to the power of 3. This means you multiply 7 by itself three times:

7 × 7 × 7.

Calculating this step by step:

1. First, multiply 7 by 7 to get 49.

2. Next, take that result (49) and multiply it by 7 again.

49 × 7 gives you 343.

Thus, 7 cubed equals 343, making it the correct answer. This mathematical operation, known as exponentiation, helps simplify calculations involving repeated multiplication and is commonly encountered in various fields, including aviation maintenance, where understanding measurements and capacities can be vital.
