Question

An aquarium in the shape of square will hold 25 gallons of water. If the volume is 3.375 cubic ft., find the length of one side?

Answer 1

Answer: The length of one side = 1.5 feet

Step-by-step explanation:

GIven: The shape of aquarium is square ( in 3d its cube).

Its volume = 3.375 cubic ft

Volume of cube = $(side)^3$

i.e. side = $(Volume)^{\dfrac13}$

Now, Side of aquarium  = $(3.375)^{\frac13} =(1.5^3)^{\frac13} =1.5$   [$1.5^3=3.375$]

Hence, the length of one side of aquarium = 1.5 feet
