Question

An aquarium has a length of 20 inches, a width of 10 inches, and a height of 18 inches. The directions tell you to fill the aquarium until you have a 2-inch gap between the top of the water level and the top of the aquarium. What is the volume of the water?

Answer 1

400 in.3
3,600 in.3
3,200 in.3
2,304 in.3

Answer 2

Your water-level height will be 18 - 2 or 16. So now, you get the volume of water by

V = w x L x h where you use the new "h" of 16. w = 10 and L = 20

Answer 3

so do i divide that

Answer 4

Actually, your volume V is:

V = w x L x h
V = 10 x 20 x 16

Answer 5

so do i do 10 times 20 times 16?

Answer 6

yes, and then you'll have the right answer.

Answer 7

3200

Answer 8

Yes, good job again. I think you're getting this.
