Storage Capacity for Rectangular Tank  

Example:
Calculate the storage capacity of a rectangular tank in cubic inches and gallons.
Length = 15 inches
Width = 10 inches
Height = 5 inches
Solution:
Apply formula:
Capacity (Cubic Inches) = Length x Width x Height
Capacity (Cubic Inches) = 15*10*5
Capacity (Cubic Inches) = 750 cubic inches
Capacity (Gallons) = capacity (cubic inches) / 231
Capacity (Gallons) = 750/231
Capacity (Gallons) = 3.2467532467532 Gallons
