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

Explanation

Out of the three numbers 1.2 has got the least number of significant figures - two. We should round off the other numbers to 2 + 1 = 3 significant figures and carry the multiplication. 2.54 has three significant figures and hence needs no rounding off. 3.257 is to be rounded off to 3.26.
`1.2 xx2.54 xx 2.36 = 9.93648`. But the result should be limited to the least number of significant digits - that is two digits only. Tue final answer should be written as 9.9 after rounding off.
