A solid metal block has mass 500g and volume 125cm³ - OCR - GCSE Maths - Question 4 - 2018 - Paper 5

To calculate the density of the block, we use the formula:

ho = rac{m}{V}

where:

• $ho$ is the density,
• $m$ is the mass (500 g), and
• $V$ is the volume (125 cm³).

Now substituting the values:

ho = rac{500 ext{ g}}{125 ext{ cm}^3} = 4 ext{ g/cm}^3

The density of the block is therefore 4 g/cm³.
