The total surface area of a cuboid is the sum of the areas of all six rectangular faces. It represents the total area that the surface of the cuboid occupies.
The calculator uses the following formulas:
Where:
Explanation: The calculator first calculates the missing width dimension using the space diagonal formula, then computes the total surface area using all three dimensions.
Details: Calculating surface area is crucial for various applications including material estimation, packaging design, heat transfer calculations, and construction planning.
Tips: Enter the length, height, and space diagonal of the cuboid. All values must be positive numbers. The space diagonal must be greater than or equal to the square root of (length² + height²).
Q1: What is a cuboid?
A: A cuboid is a three-dimensional shape with six rectangular faces, where opposite faces are equal and parallel.
Q2: Why do we need space diagonal to calculate surface area?
A: When only length, height, and space diagonal are known, the width dimension can be derived using the space diagonal formula, allowing complete surface area calculation.
Q3: What are the units for surface area?
A: Surface area is measured in square units (e.g., square meters, square centimeters, square inches) depending on the input units.
Q4: Can this calculator handle decimal inputs?
A: Yes, the calculator accepts decimal values for more precise calculations.
Q5: What if I get an error message?
A: The error indicates that the space diagonal value is too small relative to the length and height. Please verify your inputs and ensure the space diagonal is valid.
