How many cans will she need to paint the room. plz tell the answer ​

Answer 1

* is used for multiplication below

area of the four wall

= 2*(l*b) + 2*(b*h)
i.e.
= 600 + 192
= 792
area of the ceiling
= l*b
= 300
total area to be painted
= 300+792
=1092
therefore, no of cans required
1092/ 200
= 5.46
~ 6
