Astick of butter that weighs 55 grams and measures 13.0 cm, 2.0 cm, and 5.o cm for length, width, and height respectively. what is the density of the butter?

To start, you know that the formula for D=M/V where D=density, M= mass, and V=volume. Since we already know the mass is 55 grams, we now need to find the volume in order to find the density. Since we know the dimensions of the butter (we need the length, height, and width) we can find its volume by multiplying it all together: 13*2*5= 130 cm
Now, to find the density, we have to do mass divided by volume which is 55/130. This simplifies to 11/26 grams/cm and if you want your answer in decimal form, the rounded version would be about 0.423 grams/cm
