Area of all walls and ceilings and floor = use the formula= 2 (lb +bh+hl)
= 2 (15 x 10 + 15 x 7 + 10 x 7)
= 2 ( 150 + 105 + 70)
= 2 ( 325)
= 650
Therefore, Area of floor = 15 X 10 = 150
Painted area= 650 - 150= 500
As 100 m2 requires one can of paint to paint,
Therefore cans she will require to paint the room = 500 / 100 = 5 cans
