SIGNIFICANT FIGURES
1. Determine the number of significant figures in each of the following measurements:
a. 5,600mL
b. 10.5g
c. 45.00cm
e. 89,650in
f. 5,000,002m
i. 0.06080g
j. 0.7g
k. 0.092cm
m. 43,100m
n. 2.040ft
o. 90,000g
g. 6.92mL
d. 0.00566
h. 93.000lbs
l. 0.0003L
p. 1500m
2) Perform all calculations and express your answer with the appropriate sig figs & units:
a) 67cm x 55cm = _____________________
b) 4.29m x 9.83m = _____________________
d) 45.92mi ÷ 1.50hr = _____________________
c) 870mm x 430mm = _________________
e) 3200m ÷ 160sec = ___________________
f) 234.6g ÷ 67.4mL = ___________________
3) Perform all calculations & express your answers with the appropriate sig figs & units:
a) 13.531cm + 4.1cm = _____________________
b) 4.29m + 9.83m = _____________________
c) 170.2mm + 250.43mm = _________________
d) 7800cm – 2.4cm = ____________________
e) 784.326m - 2m = ______________________
f) 2.54 g - 0.000034 g = _________________
