A metal cube has a density of 8 g/cm³ and a volume of 200 cm³. What is its mass (Density of materials) ? P43-017 Density of materials checkpoint

The correct answer is 1600 g ? P43-017 density measurement and calculation.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: A metal cube has a density of 8 g/cm³ and a volume of 200 cm³. What is its mass (Density of materials) ?. The correct response is 1600 g ? P43-017 density measurement and calculation, 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 rearrange the density equation to solve for mass, volume or density. 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 43 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
