Question

Q.15 Area of four walls
room with length 4 m , breadth
3 m and height 3 m will be​

Answer 1

Answer:

36 sq.m is the correct answer.

Step-by-step explanation:

Area= L*B*H

Area=4*3*3

Area=36sq.m

Answer 2

Answer:

42 meter squared

Step-by-step explanation:

Here's your answer:

L.S.A is always equal to the area of four walls in the case of a cuboid and this room is a cuboid as the dimensions are 4m*3m*3m

We know the formula of L.S.A as 2(lh+bh)

Given values in the question are:

Length =4 meter

Breadth=3 meter

Height =3 meter

So L.S.A will be,

2(length*height+breadth*height)

Substituiting the values we get:

2(4m*3m+3m*3m)

2(12 meter squared+9 meter squared)

2*(21 meter squared)

42 meter squared is the L.S.A

As L.S.A is equal to area of four walls in the case of a cuboid

We get the area of four walls as 42 meter squared
