How many Bottles of Coca Cola in the pool?

In Math´s two of Miss Goslins Maths groups watched a video about Coca Cola, it was a big pool filled with a whole full bottle of Coca Cola bottles. The question was how many Coca Cola bottles are there all in total filling the pool? My answer is 311 all in total, comment if you want to try and answer this or give me some feedback, Bye!
