As soon as you enter the required input value(s), the Cuboid Surface Area is calculated immediately, and displaed in the output section (present under input section).
Formula
To calculate the cuboid surface area, you can use the following formula.
\(A = \) \( 2 (lh + lb + hb) \)
where
Calculation
Once you enter the input values in the calculator, the output parameters are calculated.
Examples
The following examples cover how to calcualte the Surface Area when length, breadth, and height are given.
1. What is the Surface Area of Cuboid whose length is 20 units, breadth is 10 units, and height is 15 units?
Answer
Given:
length, l = 20 units
breadth, b = 10 units
height, h = 15 units
The formula to find the Surface Area of a Cuboid is:
A = \( 2 (lh + lb + hb) \)
Substitute given values in the above formula.
A = \( 2 (20\times15+20\times10+15\times10) \)
A = 1300 square units
∴ Surface Area, A = 1300 square units
2. What is the Surface Area of Cuboid whose length is 1 units, breadth is 0.5 units, and height is 0.5 units?
Answer
Given:
length, l = 1 units
breadth, b = 0.5 units
height, h = 0.5 units
The formula to find the Surface Area of a Cuboid is:
