Answer: Rs 555 Step-by-step explanation: Length, breadth and height of a room are 5 m, 4 m and 3 m. Area of four walls of the room =2h(l+b) =2×3(5+4) =6(9) =54 sq m Area of the ceiling =l×b =5×4 =20 sq cm. Total area of the four walls and the ceiling of the room =54+20 =74 sq cm Cost of white washing = Rs 7.50 per sq m Total cost of white washing =74×7.50= Rs 555 Reply
Given:– length = 8m breadth = 6m height = 5m To find:– the cost of white washing the walls of the room and the ceiling at the rate off 7.50 per m². step-by-step solution:– Length, breadth and height of a room are 8m, 6 m and 5m. • Area of four walls of the room = 2h(l+b) => 2×5(8 + 6) => 10 × 14 => 140m² • Area of the ceiling = l×b => 8 × 6 => 48m² • Total area of the four walls and the ceiling of the room => 140 + 48 => 188m² Cost of white washing = Rs 7.50m² • Total cost of white washing => 188 × 7.50 => Rs.1410 Reply
Answer:
Rs 555
Step-by-step explanation:
Length, breadth and height of a room are 5 m, 4 m and 3 m.
Area of four walls of the room =2h(l+b)
=2×3(5+4)
=6(9)
=54 sq m
Area of the ceiling =l×b
=5×4
=20 sq cm.
Total area of the four walls and the ceiling of the room
=54+20
=74 sq cm
Cost of white washing = Rs 7.50 per sq m
Total cost of white washing =74×7.50= Rs 555
Given:–
To find:–
step-by-step solution:–
Length, breadth and height of a room are 8m, 6 m and 5m.
• Area of four walls of the room = 2h(l+b)
• Area of the ceiling = l×b
• Total area of the four walls and the ceiling of the room
Cost of white washing = Rs 7.50m²
• Total cost of white washing
