Answer 1

Question:-

Area of four walls of a room of dimensions 25m,35m,40m is

Answer :-

The area of four walls is 4800 m³

Step-by-step explanation:

Given

Dimensions of room (cuboid) :

Length = 25 m

Breadth = 35 m

Height = 40 m

To find

Area of four walls or lateral surface area

Solution

L.S.A of cuboid = 2(l + b)h

Substituting we get :-

2(25 + 35)40

2(60)40

120(40)

4800

Hence, the area of four walls or lateral surface area is 4800 m³
