Question

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

Answer 1

ceiling area = length*breadth= 15*10= 150 sq.mts
long wall area = length* height = 15*7 = 105 sq.mts
short wall area= breadth* height = 10*7= 70

now
area (one ceiling+ two long walls + two short walls) = 150+2*105+2*70 = 500 sq.mts
one paint can covers 100 sq.mts then 5 cans cover 500 sq.mts

so 5 cans needed
