Lateral surface area of a Cuboid (Rectangular box)
LSA = 2h(l + b)
Where: LSA = Lateral surface area, b = breadth, h = height, l = length
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: b = 7, h = 5, l = 10
Find: LSA_ (Lateral surface area)
- Formula: LSA = 2·h·(b + l)
- Substitute the values: LSA = 2·5·(10 + 7)
- Result: LSA = 170
Answer: LSA_ = 170
