Question

The rectangular base of an aquarium 40cm by 60 cm, and it's height is 30 cm. The aquarium is tilted along AB until the water completely covers the end ABCD. At this point, it also covers ⅘ of the base. Determine the depth of water, in centimeters,when the aquarium is level.​

Answer 1

So, we can set up the following proportion: x / 30 = 40 / 60 x / 30 = 2 / 3 x = (2/3) * 30 x = 20

So, when the aquarium is level, the depth of the water is 20 cm.
