Question

Caleb has filled his 20” x 12” x 9” fish tank 2/3 full before adding his fish. How many cubic inches of water was used to fill the tank?

Answer 1

1,440

Explanation:

So you find the volume (length times width times height) which would be 2,160 then you multiply by 2/3 which will get you to the amount of water they use to fill the tank which is 1,440 cubic inches. I hope this helps! :)
