Valerie is filling her new fish tank with water. The tank measures 36 inches by 12 inches by 20 inches. She has a bucket that she can fill with 450 cubic inches of water at the sink and then pour into the tank. What is the minimum number of times Valerie needs to fill (or partially fill) the bucket in order to completely fill her fish tank?
Your calculation is correct but the number of times she has to fill or partially fill is 19 + 1 = 20. The last fill is a partial one of 0.2 of the volume of the bucket)
