first convert the inches cubed to centimeters cubed. looking at the rate we can write 2 inches cubed = 2 * 16.39 cm cubed 32.78 cm cubed. the equation for density is D= m/v where D is the density M is the mass and V is the volume substitute the values into the equation 0.242= m/32.78 multiply by 32.78 on both sides the mass is about 7.93 grams
