Soup Can Problem

The width of the bike on my computer screen is 2 of my fingers. The whole water tank is about 5 fingers long, so the water tank is 2.5 bike widths. Googling "bike dimensions," I found that a standard bike is about 1.8m or 180cm wide, so the water tank is 2.5*180cm = 450cm long. If we assume that the water tank has the same proportions to a regular soup can, we can find the ratio of heights to find the diameter of the tank. From google, I found that the normal dimensions of a Campbell's soup can is 10.16cm x 3.33cm. So the ratio of heights 450/10.16 = 44.29. So to find the diameter of the water tank we multiply this ratio by the diameter of a regular can: 44.29*3.33 = 147.5. So the radius is 147.5/2 = 73.75. The volume of a cylinder is the area of the base times the height, so we get:

pi*r^2*h = pi * (73.75)^2 * (450) = 7,689,293 cm^3 (approximately) 

1cm^3 = 0.001 L

So 7,689,293 cm^3 = 7689.293 L 

So the water tank holds about 7,700 L of water.
