Since 1 cubic feet = 62 pounds, the weight of the water that Jerry put in the aquarium is 558 pounds
<h3>How to calculate the volume/weight of water</h3>We have to find the volume of water in the aquarium.
Recall the shape of the aquarium is a rectangular prism. Therefore,
volume = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 3 ft
w = 2 ft
h = 1.5 ft
volume = 3 × 2 × 1.5
volume of water = 9 ft³
Therefore,
1 ft³= 62 pounds
9 ft³ = ?
cross multiply
weight of water = 9 × 62
weight of water = 558 pounds
