Question

What is the cost of white washing a room 6m x 5m x 3m, if the rate of white washing is 100Rs/m^2 (assume all 4 Walls and roof need to be white washed)-
b)9600
d)3000. ​

Answer 1

Answer:

length = 6m

breadth= 5m

height = 3m

so... area of 4 walls + area of roof

2(l+b)h + l× b

2 (6+5)3 + 6× 5

2(11)3.+ 30

6× 11+ 30

66+30

96 m²

now, cost of white washing at 1m²= rs. 100

cost of white washing at 96m²= rs. 100 × 96

rs. 9600

so option b is correct 9600 rs.
