Answer:
The length of one side of the aquarium is approx. 1.5 ft.
Step-by-step explanation:
On he 'Net or in a reference book you can determine that 1 gallon has volume 0.133681 ft^3 or 231 in^3.
Thus, 25 gallons has the volume 25(0.134 ft^3), or 3.35 ft^3.
Since the aquarium has the shape of a cube, its volume is V = s^3, where s is the length of one side.
Thus we have 3.35 ft^3 = s^3, and can find s by taking the cube root of both sides of this equation:
s = (3.35 ft^3)^(1/3) = 1.496 ft, or approx. 1.5 ft.
The length of one side of the aquarium is approx. 1.5 ft.
