Math question: What is the sum of the digits of the number 1405?

To find the sum of the digits in the number 1405, we add each digit together. The digit 1 + the digit 4 + the digit 0 + the digit 5 equals 10. Hence, the sum of the digits in the number 1405 is 10.

Math Question: If 1405 is divided by 13 and then squared, what is the result?

To find the result, we first divide 1405 by 13, obtaining 107.69. Then, squaring this value yields 11583.7761. Thus, when 1405 is divided by 13 and then squared, the result is approximately equal to 11583.7761.

Math question: If 1405 is divided by 17 and then multiplied by 3, what is the resulting number?

To find the answer, we divide 1405 by 17, which gives us approximately 82.65. Next, multiplying this by 3 yields 247.95. However, since the question mentions it should be up to 500 characters long, we can round the answer to two decimal places, resulting in 247.95. Thus, the resulting number is 247.95 when 1405 is divided by 17 and then multiplied by 3.
