When the measurement 3.32 cm is multiplied by the measurement 0.02 cm.
So, the product of 3.32 cm and 0.02 cm
=
= 0.0664
Now, we have to find the number of significant figures in the number 0.0664.
Non-zero digits are always significant figures. Any zeros between two significant digits are significant figures. A final zero or trailing zeros in the decimal portion are only significant figures. The number of zeros before the non zero digits are not significant figures.
Now, Consider 0.0664
Since, The number of zeros before the non zero digit digits = 2 which are not significant figures.
And non zero digits are significant figures. So, 6,6 and 4 are the significant figures.
So, there are 3 significant figures in 0.0664.
Therefore, the answer will have three significant figures.
