1. Calculate the volume in cubic centimeters (cm³):
* Length x Width x Height = Volume
* 91.5 cm x 35.5 cm x 45.5 cm = 147,257.625 cm³
2. Convert cubic centimeters to liters:
* 1 liter (L) = 1000 cubic centimeters (cm³)
* 147,257.625 cm³ / 1000 cm³/L = 147.26 L
Therefore, your fish tank has a volume of approximately 147.26 liters.
