Rectangle prism with length 20inches, width 18inches and height 10inches. Suppose water is pumped out of the aquarium at a rate of 360in^3 per min. If the aquarium starts completely full how many mins will it take to empty it

10 minutes

Step-by-step explanation:

To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.

Mathematically, V = w h l where w, h and l are width , height and length respectively.

V = 20 * 18 * 10 = 3600 in^3

Now to get the number of minutes, we divide the volume by the draining rate.

That would be 3600/360 = 10 minutes

the correct answer is the second option
