Question

The dimensions of a wall are 16m by 12m by 8m . Calculate the area of its four walls.​

Answer 1

Step-by-step explanation:

We know the formula of finding area of a four wall of room is 2(l+b)h

here we will do

={2(16+12)8}m²

={56*8}m²

=448m²

So 448m² is the area of four walls

Answer 2

Given :-

• Length (L) = 16 m
• Breadth (B) = 12 m
• Height (H) = 8 m

To Find :-

• Area of its four wall (LSA)

Solution :-

According to the Question

It is given that ,

• The dimensions of wall are 16m by 12m by 8m respectively.

We have to calculate the area of its four wall.

• Area of four walls = 2(L+B)H

Where,

L denote Length

B denote Breadth

H denote Height

Substitute the value we get

⟶ Area of four walls = 2(16+12) 8

= 2(28)8

= 56×8

= 448 m²

Hence, the area of its four walls is 448 m².
