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

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)^(\frac13)`

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
