Final answer:

To calculate the amount of bronze needed to prepare the bronze figure, we can use the formula: Mass = Volume × Density. First, convert the volume from mL to cm³. Then substitute the values into the formula and calculate the mass. Finally, convert the mass from grams to ounces.

Step-by-step explanation:

To calculate the amount of bronze needed to prepare the bronze figure, we need to find the mass of the bronze. We can use the formula:

Mass = Volume × Density

First, we convert the volume from mL to cm³. Since 1 mL = 1 cm³, the volume of the bronze figure is 280 cm³. Next, we can substitute the values into the formula:

Mass = 280 cm³ × 8.6 g/cm³

Mass = 2408 g

Finally, we can convert the mass from grams to ounces. Since 1 ounce = 28.35 grams, the mass of the bronze figure is:

2408 g ÷ 28.35 g/oz = 85 ounces

Therefore, approximately 85 ounces of bronze are needed to prepare the bronze figure.
