Which formula gives the lateral surface area of a cuboid?
A2h times l minus b
B2l times h plus b
C2b times l plus h
D2h times l plus b
Answer & Solution
Correct answer: D. 2h times l plus b
1. Only the four side faces are counted.
2. Height multiplies the base perimeter.
3. The lateral surface area of a cuboid is given by 2h times l plus b.
4. So the answer is 2h times l plus b.
