The Giant Soup Can Puzzle

The real soup can has dimensions of 10 cm (height) and 3.5 cm (radius). So the ratio of its height to radius is 10/3.5

My bike (as an average bike) has length of 175cm. Based on the picture, it seems that the length of the tank is 2.5 times longer than the length of the bike.

So the length of the tank is estimated to be 2.5*175= 437.5 cm ~ 4.30 m

Using the above ratio, the tank’s radius is estimated to be 150 cm ~ 1.5 m.

Thus, the volume of the tank is estimated to be 30 m³.
