Question

Daniel is painting the walls and ceiling of a cuboidal hall with length, breadth and height of 15 m, 10 m and 7 m respectively. From each can of paint 100 m2 of area is painted. How many cans of paint will she need to paint the room?​

Answer 1

Answer:

4.5 cans

Step-by-step explanation:

Area of one wall = l*h = 15*7 =75m2

areas of 4 walls = 4*75 =300m2

area of ceiling= l*b = 15*10 =150m2

total painting areas= 300+150=450m2

one can =100m2

so, 450m2 = 450÷ 100 =4.5 cans
