A rectangular parallelepiped barrel with the lengths of the bottom two sides measuring 6 meters (m) 40 centimeters (cm) and 9 meters (m) respectively and the height measuring 5 meters (m) 20 centimeters (cm) is filled with sand. We want to divide this sand into several barrels whose volume is one cubic meter (m3). Find at least how many barrels you need.
