Answer 1

5425.875 in.³

Explanation:

I bought an aquarium with 39.75 inches wide and 11.375 inches deep.

Salesman advised me to keep the water 2 inches below from the top of the tank.

If tank is 14 inch high then height of water that i will keep

= 14 - 2 = 12 inch

Therefore, Volume of the water will be

= length × depth × height.

= 39.75 × 11.375 × 12

= 5425.875 in.³

it will contain water 5425.875 in.³

Answer 2

we know that

high of the water=14 in-2 in=12 in

wide=39.75 in

deep=11.375 in

so

volume of the water in the tank=39.75*11.375*(12)-----> 5,425.875 in³

the answer is

5,425.875 in³ of water
