A room is 6 m long, 5m broad
and 4m height. If all its wall
are to be covered with paper
50cm wide, the length of
the paper is:
a) 120 m
b) 88 m
c) 440m
d) 176 m​

Answer 1

Answer:

a. 88 m

Step-by-step explanation:

Lateral surface area= 2(l+b)×h

=2(6+5)×4

=88m

Answer 2

Answer:

a) 120

Step-by-step explanation:

volume of room = 4*5*6

= 120

Now area of paper = l*b

= l * 30 =120

= l = 120/30 = 40

Now we have both length and breadth

Area of Paper = l*b = 40*30

= 120 m
