Question

6. Find the lateral surface area of a cuboid with perimeter of base 240 cm and
height 5 cm.​

Answer 1

Hola mate..!!❤️

Here's ur answer =>

Perimeter of the base = 2(l+b) --(_Given)

therefore, 240 = 2(l+b)

240/2 = l+b

120 m = l+b________eq.[|]

We know that,

LSA of cuboid = 2h (l+b)

LSA of cuboid = 3(5)(120)---------{from eq. [|]}

LSA of cuboid = 1800cm^2

Therefore, Lateral Surface Area of the given cuboid is 1800cm^2.
