24

Step-by-step explanation:

3.49 to the nearest whole number is 3

7.508 to the nearest whole number is 8

Multiplying both will yield 3 * 8 = 24

Although it might be mistaken that 3.49 could be approximated to 4, this is absolutely wrong. This is because we round up all values 5 and above after the decimal to 1 while we round down all values less than 5 after the decimal to 0.

Hence be it 3.4999, since it is less than 5, it is rounded as 3 to the nearest whole number digit
