Perhaps the most famous horse race ever run in the United States was the 1938 race between two thoroughbreds named War Admiral and Seabiscuit. Seabiscuit, who stood only 15 hands high, won the race. The length unit called a "hand", which is used to measure horses, is exactly 4 inches. How tall was Seabiscuit in centimeters? Significant figures matter! Please help with this question! Thanks!
