Answer 1

A room is 8m long, 6m wide, and 4 m high.The cost of papering a room with paper 80cm wide at the rate of rs 120 per piece of 5m is 24980 Rs.

Step-by-step explanation:

The dimensions of the room are

Length L = 8m

Breadth B = 6 m

Height H = 4 m

Dimensions of the paper:

Width = 80 cm = 0.8 m

Cost of 4 sq m of paper = 120 Rs.

The surface area of the room

$=2(LB+BH+HL)$

$=2(8\times 6+6\times 4+4\times 8)$

$=2(48+24+32)$

$=208$ sq m

Cost of paper = 120 Rs/ sq m

Therefore, the cost of papering

$=120\times 208$ Rs.

$=24960$ Rs.

Hope this helps.

Answer 2

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
