The mass, in grams, of the second piece of wood is; 180 grams
How to find the density of an object?We are given;
Mass of first wood = 30 grams
Volume of first wood = 40 cubic centimeters(cm³).
The formula for the density of an object is;
Density = mass/volume
Thus
Density = 30/40
Density = 0.75 g/cm³
Now, the second piece of wood has the same density (g/cm³) and a volume of 240 cm³.
Thus;
Mass of second wood/240 = 0.75
Mass of second wood = 240 * 0.75
Mass of second wood = 180 g
