Measured value 28.7053 cm, which has six significant figures. Round the measurement to five significant figures

28.705 cm

Explanation:

Hello,

In this case, for rounding the number to five significant figures we must "cut" it at 5 so we hide the 3, therefore it turns out:

28.705 cm.

Moreover, we must realize that since such 3 is less than five, we do not modify the previous five to six, case which would happen if that three has changed to five or more.

Regards.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
