Answer:
To solve for m, you need to multiply density with volume.
Given we don't know which is the hypotenuse, either FE is, or DF is. Note it can't be DE as the hypotenuse is the longest side and you already know FE is longer than DE.
<span>According to pythagoras: </span>
<span>either FE² = DE² + DF² </span>
<span>or DF² = DE² + FE² </span>
<span>8² = 6² + x² </span>
<span>x² = 64 - 36 </span>
<span>x = √28 = 5.291... </span>
<span>Not one of the given answers so... </span>
<span>x² = 6² + 8² </span>
<span>x² = 36 + 64 </span>
<span>x = √100 = 10 </span>
<span>answer: B) 10 for the frist one</span>
