X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
<u>To find the density:</u>
⇒ must find the relationship between the density, mass, and volume
⇒ 
<u>Let's examine the information given:</u>
- weight: 1890g
- dimensions: 8cm * 5cm* 5cm
<u>Let's first find the volume:</u>
⇒ the volume is the dimensions multiplied together

<u>LEt's calculate the density now:</u>

<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>
<u></u>
