Arella needs to paint a board that is 2 meters wide and 3 meters tall. If one cup of paint will cover 1000 square centimeters, h
scZoUnD [109]

Hey!


The area of the board is 60,000 centimeters.


1 meter = 100 centimeters

2 meters = 200 centimeters

3 meters = 300 centimeters


Area = length × width

300 × 200 = 60,000


One cup covers 1,000 centimeters. To cover 60,000 centimeters, divide 60,000 by 1,000.


60,000 \div 1,000 = 60


That means Arella needs 60 cups
