Act One

How many gallons of water are in our new tank?
Act Two
 ImageA Closer Look
1 cubic foot = 7.48 gallons
The metal tank sits on a 12inch tall concrete foundation.
 Teacher noteYes, there is a reason for the zoomedin picture of the PortaPotty. Think scale factor. PortaPotties have a standard size, and don't forget that it's sitting on the dirt. My school site has 2 PortaPotties on it for game days, so students were able to recognize that they could go on a field trip to the PortaPotty. There's a first time for everything! If not, research is always good.
Act Three
 FileWater Tank Measurements
 Teacher noteWith the given measurements, have students recalculate the volume of the tank and how many gallons it will hold. Then, have them compare it to their original estimate. In this 3dimensional problem, precision makes a big difference in the students' estimates. Remember, we are looking for problem solvers. Estimation is a huge part of real life. Celebrate "close" answers.
