From the image, we can see the amount of water in Liters are in the beaker.

The beaker is marked with numbers that are skip counting by 10. (10,20,30) so on. There are 4 ticks below the 10, 5 if you count the 10.

So that means 10/5 = 2 L per tick.

The water goes above the 30 mark and under the 40 mark, which means it's somewhere in the 30's.

Since each tick is 2 L, and the water goes to the third tick:

2L + 2L + 2L = 6L.

Add 6L to 30: 30+ 6L = 36L
