5.7 potatoes were placed in a 7.3 liter cauldron, and filled with water to the top. For this, we took 2.3 liters of water. Find the density of the potato.

To find the value of the density of potatoes, we use the formula: ρк = mк / Vк = mк / (V – Vв).

Variables: mk – potato mass (mk = 5.7 kg); V is the volume of the boiler used (V = 7.3 l = 7.3 * 10-3 m3); Vw – the volume of the poured water (Vw = 2.3 l = 2.3 * 10-3 m3).

Let’s calculate: ρк = mк / (V – Vв) = 5.7 / (7.3 * 10-3 – 2.3 * 10-3) = 1140 kg / m3.

Answer: Potatoes, according to the calculation, have a density of 1140 kg / m3.
