Answer: 3ft
Explanation:
The volume of water in the aquarium is given as 11.43 cubic feet. The length of the aquarium is given as 2.6 feet and the width is 1.4 feet. Let the depth of the aquarium be 'd' feet.
Using the formula for the volume of a rectangular solid, we have:
Volume = Length x Width x Depth
Substituting the given values, we get:
11.43 = 2.6 x 1.4 x d
Simplifying, we have:
11.43 = 3.64d
Dividing both sides by 3.64, we get:
d ≈ 3.14
Rounding to the nearest whole number, the depth of the aquarium is 3 feet.
