  • <em>Answer:</em>

<em>h ≈ 0.25 cm</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

  • <u><em>density formula</em></u>

<em>d = m/V</em>

<em>V = l×w×h</em>

<em>replace</em>

<em>2.17 = 438/(40×20)×h</em>

<em>2.17 = 438/800×h</em>

<em>2.17×800×h = 438</em>

<em>1736h = 438</em>

<em>h = 438/1736</em>

<em>h ≈ 0,25 cm</em>

<em>Good luck !</em>
