18000 Hz refers to the frequency of a sound wave, not its volume. The loudness of a sound is typically measured in decibels (dB), not in hertz. Therefore, it is not accurate to say that 18000 Hz is loud. The perception of loudness depends on the amplitude of the sound wave, which is measured in decibels. **

To divide 18000 by 5, you can simply use long division. Start by dividing 18 by 5, which equals 3 with a remainder of 3. Then bring down the next digit, 0, to make 30. 30 divided by 5 equals 6 with no remainder. So, the final answer is 3600. **
