A metal block has a mass of 300 g and a density of 2.5 g/cm³. Calculate the volume of the metal block (Density of materials) ? P43-053 Density of materials checkpoint

120 cm³ In P43-053, the answer must mention density, mass, volume and connect it to Density of materials.

Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. This question asks: A metal block has a mass of 300 g and a density of 2.5 g/cm³. Calculate the volume of the metal block (Density of materials) ?. The correct response is 120 cm³ In P43-053, the answer must mention density, mass, volume and connect it to Density of materials., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Density of materials, the marking point should connect directly to calculate volume when mass and density are known. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Changes of state and the particle model, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 40 is distinct because it uses this exact question context and the cause lens rather than a generic particle-model sentence.
