Example Question #1 : Volume Of A Rectangular Solid
An aquarium takes the shape of a rectangular prism 60 centimeters high, 60 centimeters wide, and 120 centimeters long. One-fourth of a cubic meter of water is poured into the aquarium after it has been emptied. How much more water can it hold?
One cubic meter of water is equal to cubic centimeters; one-fourth of a cubic meter is 250,000 centimeters. The volume of the aquarium is
cubic centimeters.
Therefore, after having one-fourth of a cubic meter of water poured in, there is room left for
cubic centimeters of water.
Example Question #1 : Volume Of A Rectangular Solid
A large aquarium has a rectangular base nine meters square and is ten and one-half meters high. The eight inlet pipes used to fill the aquarium does so at a rate of 200 liters per minute each. To the nearest hour, how long does it take for all eight pipes working together to fill the aquarium to 80% capacity?
You will need the conversion factor 1 liter = 1,000 cubic centimeters.
The aquarium is a rectangular prism with dimensions 9 meters by 9 meters by 10.5 meters, each of which can be converted to centimeters by multiplying by 100. So the dimensions are 900 cm x 900 cm x 1,050 cm, and the volume is the product of the three, or
or
80% of this is
Each pipe fills the aquarium at 200 L per minute, so the eight pipes working together fill it at a rate of 1,600 L per minute. Divide, and the aquarium is filled at 80% capacity in
In hours, this is
so 7 hours is the correct response.
