Question

10. The length, breadth and height of a cuboidal shaped room are 15m,6m and 0.5m respectively. Find the cost of painting its four side walls if cost per m ^ 2 is 50. *​

Answer 1

Answer:

Cost of painting = 1050

Step-by-step explanation:

LSA of cuboid = 2h(l+b)

2 * 0.5 (15 + 6)

1 (21)

LSA of cuboid = 21m^2

Cost of painting 1m^2 = 50

Cost of painting 21m^2 = 21 * 50

= 1050
