Area of 4 walls of the room = 2(lb + bh + hl)
=2(10×8+8×5+5×10)m^2.
=2(80+40+50)m^2
=2 × 170 m^2
=340m^2

Given :
A room is 10m×8m×5m.
To Find:
find the area of its 4 walls and the floor
Solution:
Length of room = 10 m
Breadth of room = 8 m
Height of room = 5 m
Area of 4 walls=2(l+b)h=2(10+8)(5)=180 sq.m.
Area of floor =
Area of 4 walls+area of floor = 180+80=260 sq.m.
Hence The area of its 4 walls and the floor is 260 sq.m.
