Question

and base measurements 9 in. by 18 in. About how many gallons of water does the aquarium hold?

Answer 1

Hey there!

Here's the answer.

V=lwh --> Write the volume of a rectangular prism.
V=(15)(9)(18) --> Substitute the known values.
V=2430 in^3 --> Multiply 15, 9 and 18.
V=2430 in^3/231 in^3 --> A gallon fills 231 in^3. So divide this with the volume of the aquarium.
V=10.52 gallons Approximate the answer.

So the aquarium can hold about 10.52 gallons or 11 gallons.

Hope it helps!
