and height is 6 m. Also, find the cost of white-washing the wall, if the rate of
white-washing is 5 per sq. m. doors, windows and other opening be ignored​

Answer 1

Step-by-step explanation:

area of 4walls= 2(l+b)h

= 2(10+8)6

= 2*18*6

= 216m2

cost of 1m2 =5

cost of 216 m2 = 216*5

=. 1080

Answer 2

Answer:

Rs.1080

Step-by-step explanation:

Perimeter of the floor= 2*(10+8) =36 m

height= 6 m

Area of the four walls= perimeter of floor*height

= 36*6 m^2

Total cost for white washing= Rs. 36*6*5

= Rs.1080
