72 inches
30 inches
The tail stick's out about a foot from the horses rump.
If it is not trimmed, a horses tail will reach down about 5 feet.
This is called the mane. The hair that dangles between a horse's ears is called the forelock.
The mythological Chimera had the head of a lion, body of a goat and a serpent for a tail.
They stand head to tail to help each other swish flies away. They both swing their tails at the other horse's face to discourage flies.

Well, honey, if the head is as long as the tail, that means each is 15 inches. If you double the head length to 30 inches and keep the tail at 15 inches, you get a total of 45 inches, with the body being 18 inches. So, the head is 30 inches, the tail is 15 inches, and the body is 18 inches. Voilà!
