Calculating volume by combining the volume of simple shapes

A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 21.0 long by 21.0cm wide by 14.0cm deep.In addition, as shown in the sketch below, the student needs to allow 2.0cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 11.5cm will be just barely submerged in the water.Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.1L
