I NEED HELP, IF LINK = REPORT FOR MODERATORS TO MODERATE (I think they should start something that doesn’t let us post links)

Answer:
1. 3,168 in³
2. [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
1. The total volume of the tank - as calculated by the formula for a rectangular prism - [tex]V=LWH[/tex], where L is length, W is width, and H is height. 15 · 24 · 11 = 3,960 in³. Next, we divide 3,960 by five to get 792. If 792 in³ is the air at the top, we can then subtract that from 3,960 and get 3,168. So there are 3,168 in³ of water in the tank.
2. If we dump 3,168 in³ of water into a 12,672 in³ tank, then [tex]\frac{3,168}{12,672}[/tex] of the tank will be full. Simplified, that is [tex]\frac{1}{4}[/tex]. So that means [tex]\frac{3}{4}[/tex] of the tank will be empty.
Hope this helps! Feel free to ask any questions!
