1.	Hal is painting the four walls and ceiling of his bedroom. The bedroom is 6 m long, 4.5 m wide and 3 m high. Paint comes in 4 L cans. One litre of pain covers 10 square metres. What is the area Hal needs to paint and how many cans are needed?
Answer» Length of the wall =6mBreadth of the wall = 3mLength of the ceiling =4.5mBreadth of the ceiling =3mThe area that could be PAINTED in 1 litre =10m^2 1 Can contains 4 Litres of paint. Now, The total area need to be painted = area of 4 walls +1 ceiling Since ,area of the 4 walls = 4x(6x3) m^2 = 4 X 18m^2 =>72m^2Area of the ceiling = lxb=> 4.5 x 3 m^2 = 13.5m^2Hence, the area needed to be painted by Hal=72+13.5 m^2 = 85.5 m^2. ANS. the Litres of paint required to paint 85.5 m^2 =85.5m^2/10m^2 per litre = 8.55 Litres Since The number of cans required =8.55/4 =2.13.... Cans =3 Cans Ans. Hope it's helpful for you
