Answer:

Total Cost for Papering the 4 walls of the room = Rs 3,360.00

Step-by-step explanation:

Hope we are doing the papering only on the 4 walls

Length of Room , L= 8 M

Width of Room, W = 6 M

Height of Room , H =  4 M

Wall Area = 2 (LH + WH)

= 2 ((8 x 4) + (6 x 4))

= 2 (32 + 24)

= 2 x 56

= 112 Sq. Meter

Area of one paper Roll = Length of Paper x Width of paper

= 5 M x 80 CM

= 5 M x 0.80 M

= 4 SQ. METER

No of rolls required = 112 / 4

= 28 Rolls

Cost of one roll of paper = Rs 120.00

Therefore Total Cost for Papering the 4 walls of the room = 120 x 28

= Rs 3,360.00
