Find the product of 1.2, 2.54 and 3.257 with due regard to significant figures.

Text Solution

Verified by Experts

Out of the three numbers 1.2 has got the least num- ber of significant figures - two. Wc should round off the other numbers to 2+ 1 =3 significant figures and carty the multiplication. 2.54 has three significant figures and hence needs no rounding off. 3.257 is to be rounded off to 3.26.
`1.2xx2.54xx3.26=9.93648` . But the result should be limited to the least number of significant digits-that is two digits only. The final answer should be writen as 9.9 after rounding off.
