The formula for lateral surface area of cuboid is a)2h (l + b)b)2l (h ...
Explanation:
A cuboid is a 3-dimensional figure that has six rectangular faces. The lateral surface area of a cuboid is the area of the four vertical rectangular faces, excluding the top and bottom faces.
Let's consider a cuboid with length (l), breadth (b) and height (h).
Formula for Lateral Surface Area of Cuboid:
The formula for the lateral surface area of a cuboid is:
Lateral Surface Area of Cuboid = 2h(l+b)
Proof:
To find the lateral surface area of a cuboid, we need to add the areas of all the four vertical rectangular faces.
- The area of the first vertical face = l x h
- The area of the second vertical face = b x h
- The area of the third vertical face = l x h
- The area of the fourth vertical face = b x h
Adding all these areas, we get:
Lateral Surface Area of Cuboid = lh + bh + lh + bh
= 2lh + 2bh
= 2h(l+b)
Therefore, the formula for the lateral surface area of a cuboid is 2h(l+b).

We can see that the lateral surface area of area 1 + area2 + area3 + area4 + area5 + area6
=h x l + b x l + h x b + h x l + b x h + b x l
=2(h x l + b x l + h x b)
=2(lb + bh + hl)
h, l, b represents height, length, breadth respectively.
