Key Insights
A rectangular box with these exact dimensions has all sides meeting at right angles. Its surface area—the total area of all the inner and outer faces—is calculated using the formula:
2(lw + lh + wh), where l = length, w = width, h = height.
Plugging in the values:
Surface Area = 2 × (12×8 + 12×5 + 8×5) = 2×(96 + 60 + 40) = 2×196 = 392 square centimeters.
This precise math reveals how thoughtful measurement enables accurate planning—from packaging to manufacturing—highlighting why even small rectangular dimensions matter in complex systems.
