there are 55 squares in the bingo card

Usually 25 squares
40 liters, since 50cmx40cmx20cm=40000cm and cm3 can be converted into ml so it will equal 40000ml and that would equal 40liters (1liter=1000ml)
If you mean how many mm in 20cm then there are 200mm
The easiest way to reason this is to consider how you could connect nine squares together while leaving the largest amount of perimeter exposed. In other words, what's the largest number of faces you can leave exposed on a set of squares that are all connected? The answer is that if you connect all of the squares in a line, then the two end squares will have three faces exposed and the other seven squares will have two faces exposed. That gives you 2 * 7 * 2cm + 3 * 2 * 2cm = 28cm + 12cm = 40cm. So the maximum perimeter you can get is 40cm. There are many other ways that you can arrange the squares to give you the same perimeter (eg. a plus sign, a zig-zag, and so on), but none that will give you more.
