How to Calculate the Surface Area of the Box

Start with the given:

• Volume = 360 cubic inches
• Height (h) = 5 inches
• Length (l) = 2 × Width (w)

Volume formula:
Volume = length × width × height
360 = (2w) × w × 5
360 = 10w²

Solve for width:
w² = 360 ÷ 10 = 36
w = √36 = 6 inches

So:

• Width = 6 inches
• Length = 2 × 6 = 12 inches
• Height = 5 inches

Surface area of a rectangular box uses:
SA = 2(lw + lh + wh)

Plug values in:
SA = 2[(12×6) + (12×5) + (6×5)]
SA = 2[72 + 60 + 30] = 2 × 162 = 324 square inches

This surface area tells us the total area of all six sides—critical for material costs, insulation needs, and aesthetic finishes.
