How many liters in a 4 x 2 fish tank?

To determine the volume and, ultimately, the number of liters in a 4 x 2 fish tank, we must first convert the dimensions from feet to inches:

4 feet = 4 * 12 = 48 inches

2 feet = 2 * 12 = 24 inches

Now, we can calculate the volume of the fish tank using the formula for the volume of a rectangular prism:

Volume = Length x Width x Height

Volume = 48 inches x 24 inches x 18 inches

Volume = 23040 cubic inches

To convert cubic inches to liters, we divide by 61.0237:

Volume in Liters = 23040 cubic inches / 61.0237

Volume in Liters ≈ 377.04 liters

Therefore, a 4 x 2 fish tank has approximately 377.04 liters of volume.
