Question

an aquarium at sea world is 10ft long, 3ft wide, and is filled with water to a depth of 7ft. water weighs 62.4 pounds per cubic foot. A.) what is the volume of the water in the tank? B.) what is the weight of the water of the water in the tank?

Answer 1

Let's find the volume of the tank by l×w×h
10×3×7
30×7
210 ft³
So the volume of the water in the tank is 210 ft³.
Now, since it is 62.4 pounds per cubic foot, we have to multiply.
62.4×210
13,104
The weight of the water in the tank is 13,104 lbs.

Answer 2

The volume of the tank is 210m
The weight is 17,640

This is my answer I believe it’s right but I’m not sure.
