Determine the mass of a rectangular pine block having a length of 10 cm, a width of 8 cm and a height of 5 cm, the density of a pine p kg / m3 = 400; p g / cm3 0.40
In our task, we need to find the mass by the formula m = V * p, where the volume is the multiplication of the bar’s measurements, and the density was initially given to us by condition, thus V = 0.1 * 0.08 * 0.05 = 0.0004 (we have already converted everything to meters ) cubic meters, and now we find the mass = 0.0004 * 400 = 0.16 kilograms, that is, 160 grams.
