Final answer:
When multiplying numbers with significant digits, round the product to the same number of significant figures as the number with the fewest significant figures. The product of 603cm and 24cm, rounded to two significant figures, is 14000cm².
Step-by-step explanation:
When multiplying numbers, the result should be rounded to the same number of significant figures as the number with the fewest significant figures.
In this case, 603cm has three significant figures and 24cm has two significant figures. Therefore, the product should be rounded to two significant figures.
When multiplying 603cm and 24cm, the result is 14472cm². Rounding to two significant figures gives us 14000cm².
So, the product of 603cm and 24cm, rounded to two significant figures, is 14000cm².
