A 15 cubic-foot aquarium is advertised as 2 feet tall and 3 feet wide. How deep is it?
15 / 6 = 2.5 feet
To find the depth of the aquarium, we can use the formula for volume:
Volume = Length × Width × Height
Given that the volume is 15 cubic feet, the height is 2 feet, and the width is 3 feet, we can substitute these values into the formula:
15 = Length × 3 × 2
To isolate the length, divide both sides by (3 × 2):
15 ÷ (3 × 2) = Length
Simplifying this expression:
15 ÷ 6 = Length
Length = 2.5
Therefore, the depth of the aquarium is 2.5 feet.
