WebThe answer is calculated by multiplying 10.5 inches by 4. The number 10.5 has 3 significant figures. The number 4 is an exact number; you count, and not measure, that there are 4 sides to a square. The number of sides is thus considered to have an infinite number of sig figs and should not limit the certainty of the perimeter. WebThe number 47.4 has THREE significant figures because all of the digits present are non-zero. Zeros between two non-zero digits are significant. For example, 4098 has FOUR …
