Answer:
290.32 g
Explanation:
First we <u>calculate the volume</u> of the cube:
- Volume = (3.20 cm)³ = 32.768 cm³
Now we <u>convert cubic centimeters to mililiters</u>:
- 32.768 cm³ * 1 mL / 1 cm³ = 32.768 mL
Finally we <u>calculate the mass</u>, using the <em>equation for density</em>:
- mass = 8.86 g/mL * 32.768 mL = 290.32 g
