Expert Answer
length, l = 4.234 m - length has 4 signifcant figures
breadth, b = 1.005 m - breadth has 4 significant figures
thickness, h = 2.01 cm = 0.0201 m - height or thickness has 3 significant figures.
Thus, the area and volume must have 3 significant figures in its final value after calculation.
