Detailed Explanation of Calculations

To illustrate how to arrive at the volume calculations, let’s break down a few examples in detail:

  1. Example 1 – Rectangular Prism Volume of 10 Feet by 5 Feet by 4 Feet:
    • Formula Used: V = l × w × h
    • Calculation: V = 10 × 5 × 4 = 200 cubic feet.
    • Conversion to Liters: Volume in liters = 200 × 28.3168 = 566.56 liters.
    • Application: This is ideal for calculating the storage capacity of a box measuring 10 feet long, 5 feet wide, and 4 feet high.
  2. Example 2 – Cube Volume of 6 Feet:
    • Formula Used: V = s³
    • Calculation: V = 6³ = 216 cubic feet.
    • Conversion to Liters: Volume in liters = 216 × 28.3168 = 612.24 liters.
    • Application: This calculation is suitable for estimating the volume of a cubic storage container with each side measuring 6 feet.
  3. Example 3 – Cylinder Volume with Diameter of 3 Feet and Height of 5 Feet:
    • Formula Used: V = π × (r²) × h
    • Calculation:
      • Radius (r) = Diameter / 2 = 3 / 2 = 1.5 feet.
      • V = π × (1.5)² × 5 ≈ 35.34 cubic feet.
    • Conversion to Liters: Volume in liters = 35.34 × 28.3168 = 100.00 liters.
    • Application: Useful for measuring the volume of a cylindrical water tank with a diameter of 3 feet and height of 5 feet.
  4. Example 4 – Sphere Volume with Diameter of 6 Feet:
    • Formula Used: V = (4/3) × π × (r³)
