Answer: 2. The area of a square with sides 2.50 cm long is:

Area = side × side = 2.50 cm × 2.50 cm = 6.25 cm²

The thickness of the platinum sheet is 0.25 mm, which is equivalent to 0.025 cm.

Therefore, the volume of the platinum sheet is:

Volume = Area × thickness = 6.25 cm² × 0.025 cm = 0.15625 cm³

So, the volume of the platinum sheet is 0.15625 cm³.

Explanation: 3 To convert milliliters (mL) to liters (L), we need to divide the volume in milliliters by 1000.

So, to convert the volume of a wine bottle from 750 mL to liters, we can use the formula:

Volume in liters = Volume in milliliters ÷ 1000

Plugging in the values, we get:

Volume in liters = 750 mL ÷ 1000 = 0.75 L

Therefore, a standard wine bottle has a volume of 0.75 liters.
