Answers.Body: <p>According to <a href="https://www.quora.com/What-is-the-volume-of-plastic-in-a-4x2-Lego-brick" rel="noreferrer">this Quora post</a>, the volume of ABS in a <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=3001" rel="noreferrer">standard 2x4 brick</a> is 2.4824 cubic centimeters, which is <strong>34.13g of 14k gold</strong> (assuming this brick is the same as standard mold).</p>
  <p>Copied math from Quora in case link dies:</p>
  <blockquote>
  <p>According to BrickLink, a 2x4 LEGO brick is about 2.32g. And the median density of ABS plastic (which is what most LEGO is made out of) is around 1.07 g/cm^3. That would put the volume of plastic in a LEGO element around roughly 2.4824 cubic centimeters.</p>
  </blockquote>
  <p>2.4824 * 13.75 g/cm^3 (avg density of 14k gold) = 34.13g.</p>

Answers.Text: @Valorum, I wouldn't say it is incorrect. Upon closer inspection it is clear that LEGO didn't use exactly the same mould to produce this gold brick they use for platic bricks. One obvious thing - absence of LEGO logo on studs. This means alternative production means were utilised here. And if I'm reading correct gold shrinks when cooled down - which means final brick will be smaller than the mould. Taking these both statements into account could explain the discrepancy.

  According to [this Quora post](https://www.quora.com/What-is-the-volume-of-plastic-in-a-4x2-Lego-brick), the volume of ABS in a [standard 2x4 brick](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3001) is 2.4824 cubic centimeters, which is **34.13g of 14k gold** (assuming this brick is the same as standard mold).
