George and phil were playing with their fish tank again. they had a difficult time keeping their fish tank is 100 cm long, 60 cm wide and 40 cm high. they tilted the tank resting on a 60 cm edge, with the water level reaching the midpoint of the base. when they rest the tank down to a horizontal position, what is the depth of the water in cm?


Draw a side view of the tank, and assume they tilted it until the water reached the mid-point of the base because it started spilling over the top edge. A drawing will show a triangle with a base of 50 cm and a height of 40 cm in that position. The area formula (you should know) gives 1000 cm2 x 60 cm for 60,000 cm3 of water.
Since the base area is 6,000 cm2, the water will be 10 cm high (vol/area base).
Tough on fish though....
