Question

What is the lateral surface area area of a cuboid​

Answer 1

Lateral surface area - The sum of surface areas of all sides except the top and bottom face of solid is defined as the lateral surface area of a solid. So the lateral surface area (L.S.A) of the cuboid is = 2(lh+bh)=2h(l+b)

Answer 2

Lateral surface area of a cuboid = 2h(l + w)

where w = width, l = length and h = height

Explanation:

Lateral Surface Area = Total Surface Area - Area of top and bottom faces

Let w = width

Let l = length

Let h = height

Lateral Surface Area = 2(lw + wh + lh) - (2 × l × w)

= 2lw + 2wh + 2lh - 2lw

= 2lh + 2wh

= 2h(l + w)
