A fish tank is 3 feet by 4 feet by 5 feet. How many gallons of water will it hold? A cubic foot of water is 7.5 gallons.

Answered by admin @ 29/10/2021

Answer:

The fish tank will hold 450 gallons of water.

Step-by-step explanation:

The fish tank has a rectangular prism shape, therefore it's volume is given by the following expression:

volume = length*width*height

Applying the data from the problem, we have:

volume = 3*4*5

volume = 60 feet³

Since 1 feet³ is equal to 7.5 gallons, then:

volume = 60*7,5 = 450 gallons.

The fish tank will hold 450 gallons of water.
