Express the product of 5.4 mm and 6.02 mm using the correct number of significant digits. a. 32 mm^2b. 33 mm^2c. 32.5 mm^2d. 32.51 mm^2

we are asked to multiply 5.4 mm by 6.02 mm

5.4 mm has 2 significant figures

6.02 mm has 3 significant figures

When multiplying these 2 numbers the answer should have the least number of significant figures

From the 2 numbers the least number of significant figures is 2 , therefore answer should be rounded off to 2 significant numbers

5.4 x 6.02 = 32.5 rounded off is 33

Answer is b. 33 m^2
