Ow many cans of paint are needed to cover an area of 2,200 square units if one can of paint covers an area of 400 square units?

The number of cans needed to paint an area covering 2,200 sq. units will be given by:

number of cans=[area required to be painted]/[area that 1 can of paint can cover]

=2200/400

=5.5

Therefore we conclude that we will need 5.5 cans of paint
