A fishtank measures 11 ft X 18 ft X 12 ft in English dimensional units. If water weights 62.4 lbs/ft3, what is the weight in lbs of the water filling the tank?
find volume of tank in cubic feet.
11 x 18 x 12 = ? cubic feet.
Then (62.4 lbs/ft^3) x ? cubic feet = weight water in lbs.
To find the weight of the water filling the tank, we need to calculate the volume of the tank and then multiply it by the weight of water per unit volume.
To calculate the volume of the fishtank, we multiply the length, width, and height:
Volume = length × width × height
In this case, the length is 11 ft, the width is 18 ft, and the height is 12 ft. Plugging in these values, we have:
Volume = 11 ft × 18 ft × 12 ft
Next, we multiply the volume by the weight of water per unit volume, which is 62.4 lbs/ft^3:
Weight = Volume × Weight per unit volume
Substituting the values we have:
Weight = (11 ft × 18 ft × 12 ft) × 62.4 lbs/ft^3
Now, let's calculate the weight of the water:
Weight = 2,376 lbs
Therefore, the weight of the water filling the tank is 2,376 lbs.
