Density formula in maths
WebDensity Formula Questions. 1) You are packing for a trip to Mars. You are given a cubical box to pack that is 1.71 m on a side. Due to fuel and space limitations, the final density, ρ, of your box must be no more than 2 kg/m 3. What is the largest mass you can pack? Answer: The volume, V = (1.71 m x 1.71 m x 1.71 m) = 5.000 m 3 for cubical box. WebThe formula for density is d = M / V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth ’s density is 5.51 grams per cubic centimetre.
