> a square storage bin measures 15 feet on a side filled with corn 15ft length * 15ft width * 15ft height = 3375 cubic ft 1 bushel = 1.25 cubic ft 3375 cubic ft / 1.25 cubic ft = number of bushels Answer: 2700 bushels

height = time * 48ft/s 35ft = time * 48ft/s 35ft/(48ft/s) = time time = 0.72917 seconds
