Answer:
6
Step-by-step explanation:
You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units. So, you'll need:
2200 sq units / 400 sq units/can = 5.5 cans
In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.
So, in total you will need 6 cans of paint to cover all 2,200 sq units.
