The difference of the third bar and the first is the volume of the cup. 450 cm^3 - 370 cm^3 = 80 cm^3 Since the second bar corresponds to the addition of two cups if water, and by subtracting the volume of the two cups of water, we get the volume of water originally in the cubic container. 410 cm^3 - 160 cm^3 = 250 cm^3 Since 1/4 of the volume of the cubic container is 250 cm^3, the volume of the cubic container is 1000 cm^3. Hence the side of the container is 10 cm.

Solving this question by ratio is easier than using models. It requires a bit of thinking of how to use ratio effectively though. paragraph 2 tells us that if A is filled at 4L/min and B is filled at 6L/min, they will be completely filled at the same time. that means the capacity ratio for A:B is 4:6, simplified to 2:3, multiplied to 6:9. In paragraph 1, the tanks are being filled in ratio 3:5. So the filling ratio every 2 mins is 6:10. Comparing with the capacity ratio, this tells us that tank B is being filled with an EXTRA 1L every 2 mins (remember that the capacity ratio is 6:9, so that means you would want 6L in A for every 9L in B, regardless of the time taken) As tank B overflowed by 5L, it means that the taps were switched on for 10mins in paragraph 1. Therefore, capacity of A is 3x10=30L. Following the capacity ratio, B is 45L
