How many cans of paint are needed to cover an area of 2200 square units if one can of paint covers in area 400 square units

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.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
