Can my family bring the equivalent of 40,000 baht in US dollars to Thailand?

A family of 5 visiting Thailand in July inquired if they can present the equivalent of 40,000 baht in US dollars upon entry. Multiple comments confirmed that any major currency is acceptable, including dollars, as long as the amount is equivalent to 40,000 baht. It's essential that the currency is in new, clean bills for easier exchange later. Some users noted that they have never been asked for proof of funds when entering Thailand.
