How much does a 40mm steel ball weigh?

Views: 421 Update Date:Apr 12 , 2024
The weight of a 40mm steel ball can vary depending on the exact type of steel and its density. However, a rough estimate can be made assuming a standard steel density of around 7.85 grams per cubic centimeter.

Using the formula for the volume of a sphere (4/3 * π * r^3), where r is the radius (half the diameter), we find:
Volume = (4/3) * π * (2 cm)^3 ≈ (4/3) * π * 8 cm^3 ≈ 33.51 cubic centimeters

Now, multiplying the volume by the density, we get the weight:
Weight ≈ 33.51 cm^3 * 7.85 g/cm^3 ≈ 263.14 grams

So, a 40mm steel ball would weigh approximately 263.14 grams. Keep in mind, this is an approximate calculation and actual weights may vary slightly depending on factors such as the exact composition of the steel.
