Question

write the lateral surface area of a cuboid whose length,breadth and height are respectively l,b and h​

Answer 1

Step-by-step explanation:

To find the lateral surface area of the cuboid, we need to add the area of each lateral side. 

Two sides will have the dimensions b and h. 

Other two sides will have the dimensions, l and h.

Each wall is in the shape of a rectangle.

Hence, Lateral surface area of the cuboid =2(b×h)+2(l×h)=2(l+b)h
