Introduction

In this article, we will guide you through the steps to calculate the density of a steel hex nut. Density is a fundamental physical property that is defined as the mass per unit volume of a substance. It is an essential parameter in various fields, including physics, engineering, and chemistry. To calculate the density of the steel hex nut, we need to know its mass and volume.

Step 1: Calculate the Volume of the Prism

The steel hex nut has two regular hexagonal faces and a hole with a diameter of 0.4 cm through the middle. To calculate the volume of the prism, we need to find the area of the hexagonal faces and multiply it by the height of the prism.

Area of a Regular Hexagon

A regular hexagon can be divided into six equilateral triangles. The area of an equilateral triangle with side length s is given by:

A = (√3/4) * s^2

Since the hexagon has six equilateral triangles, the total area of the hexagon is:

A = 6 * (√3/4) * s^2

Area of the Hexagonal Face

The steel hex nut has a regular hexagonal face with a side length of 0.4 cm. We can use the formula above to calculate the area of the hexagonal face:

A = 6 * (√3/4) * (0.4)^2 A = 6 * (√3/4) * 0.16 A = 0.24 * √3 A ≈ 0.4157 cm^2

Volume of the Prism

The volume of the prism is given by the product of the area of the hexagonal face and the height of the prism. Since the height of the prism is not given, we will assume it to be h cm. The volume of the prism is:

V = A * h V = 0.4157 * h V ≈ 0.4157h cm^3

Volume of the Hole

The steel hex nut has a hole with a diameter of 0.4 cm through the middle. The volume of the hole is given by:

V = π * (0.2)^2 * h V = 0.04πh cm^3

Volume of the Prism with the Hole

The volume of the prism with the hole is given by the difference between the volume of the prism and the volume of the hole:

V = 0.4157h - 0.04πh V ≈ 0.4157h - 0.1257h V ≈ 0.29h cm^3

Mass of the Steel Hex Nut

The mass of the steel hex nut is given as 3.03 grams.

Density of the Steel Hex Nut

The density of the steel hex nut is given by the ratio of its mass to its volume:

ρ = m / V ρ = 3.03 / 0.29 ρ ≈ 10.41 g/cm^3

Conclusion

In this article, we have guided you through the steps to calculate the density of a steel hex nut. We have calculated the volume of the prism with the hole and used it to find the density of the steel hex nut. The density of the steel hex nut is approximately 10.41 g/cm^3.
