The given question is a multiplication problem that requires finding the product of 3 and 12. When multiplying a single digit number (3) by a double-digit number (12), we can use the standard multiplication method. Multiply 3 by the ones digit of 12, which is 2, resulting in 6. Then, multiply 3 by the tens digit of 12, which is 1, resulting in 30. Finally, add these two products together, 6 and 30, to get the final answer of 36.
