The water should fill the aquarium to 1.5 feet
Solution:
Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.
This means volume of aquarium is 9 cubic feet
Given that aquarium is 2 feet wide and 3 feet long
To find: Height of aquarium
Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula
The volume of cuboid is given as:
volume of cuboid = [tex]l \times w \times h[/tex]
Where "l" is the length
w is the width
"h" is the height
Substituting the values, we get,
[tex]9 = 3 \times 2 \times h\\\\9 = 6 \times h\\\\h = \frac{9}{6} = 1.5[/tex]
Thus the height of aquarium is 1.5 feet
