Question

The total surface area of cuboid of length \(l\), breadth \(b\), height \(h\) is _____.

• A. \(2(lb + bh + hl)\)
• B. \(2h(l+b)\)
• C. \(lbh\)
• D. \(lb+bh+hl\)

Hint:

Remember: \[ \text{Cuboid TSA} = 2(lb + bh + hl) \] and: \[ \text{Cuboid Volume} = lbh \] Students often confuse TSA with volume, so always check whether the question asks for “surface area” or “volume”.

Answer 1

The Correct Option is A
