There are 125 blades of grass in a square cm of lawn. assuming the grass stand is even, how many blades of grass would be found in a lawn measuring 8 meters by 6 meters? use scientific notation in your answer.
Given : An area of 1 cm² of lawn holds 125 blades of grass.
Note that 1 m = 10² cm. Therefore a lawn measuring 8 m by 6m has an area of (8 x 10² cm)*(6 x 10² cm) = 48 x 10⁴ cm². The number of blades of grass it will hold is (48 x 10⁴)*125 = 6 x 10⁷
