Example Question #1 : Finding Volume Of A Rectangular Prism
An aquarium is shaped like a perfect cube; the perimeter of each glass face is meters. If it is filled to the recommended
capacity, then, to the nearest hundred cubic liters, how much water will it contain?
Insufficient information is given to answer the question.
Note:
A perfect cube has square faces; if a face has perimeter meters, then each side of each face measures one fourth of this, or
meters. The volume of the tank is the cube of this, or
cubic meters.
Its capacity in liters is liters.
of this is
liters.
This rounds to liters, the correct response.
