The volume of the wooden block is given by the formula V = l*w*h, where l is the length, w is the width, and h is the height. Substituting the given values, we get V = 2 cm * 5 cm * 10 cm = 100 cubic cm.
The mass of the wooden block is given by the formula M = V*d, where d is the density of the wooden block. Substituting the given values, we get M = 100 cubic cm * 18.2 g/cubic cm = 1820 g.
Therefore, the mass of the wooden block is 1820 grams.
