# Thread: Volume of a tank

1. ## Volume of a tank

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

where is the sketch? attach the file please

3. Take the total volume of the container - volume of the flask - the volume of the top portion with no water.

That boils down to:
Volume of total tank = $30 * 13 * 11 = 4290 cm^3$
Volume of flask = $\frac{4}{3}\pi r^3 = \frac{4}{3}\pi 4.25^3$
Volume of open top = $30 * 13 * 2 = 780$
