Practical Examples
Example 1 Standard Aquarium
A 24" × 12" × 18" aquarium:
Volume = 24 × 12 × 18 = 5,184 cubic inches
Gallons = 5,184 × 0.004329 = 22.44 gal
Liters = 22.44 × 3.78541 = 84.94 L
Example 2 Water Storage Tank
A 48" × 24" × 36" storage tank:
Volume = 48 × 24 × 36 = 41,472 cubic inches
Gallons = 41,472 × 0.004329 = 179.53 gal
Liters = 179.53 × 3.78541 = 679.62 L
