Asteel hex nut has two regular hexagonal faces and a hole with a diameter of 0.4 cm through the middle. its mass is 3.03 grams. complete the steps to calculate the density of the steel. calculate the volume of the prism. recall that the area of a hexagon is times the apothem times the perimeter. v = cm3 calculate the volume of the cylinder. round to the nearest hundredth. v = cm3 find the volume of the composite figure. v = cm3 calculate the density by dividing the mass by the volume. d = g/cm3
