The length of the base edge of a pyramid with a regular hexagon base is represented as [tex]x[/tex]. The height of the pyramid is 3 times longer than the base edge.

1. The height of the pyramid can be represented as [tex]3x[/tex].

2. The area of an equilateral triangle with length [tex]x[/tex] is [tex]\frac{x^2 \sqrt{3}}{4}[/tex] square units.

3. The area of the hexagon base is [tex]6[/tex] times the area of the equilateral triangle.

4. The volume of the pyramid is [tex]\frac{1}{2} x^3 \sqrt{3}[/tex] cubic units.



Answer :

To solve the problem, let’s break it down step-by-step:

1. Height of the Pyramid:
Given that the height of the pyramid is 3 times the length of the base edge [tex]\(x\)[/tex], we can represent the height [tex]\(h\)[/tex] of the pyramid as:
[tex]\[ h = 3x \][/tex]

2. Area of the Equilateral Triangle:
The area of an equilateral triangle with side length [tex]\(x\)[/tex] is given by:
[tex]\[ \text{Area of an equilateral triangle} = \frac{x^2 \sqrt{3}}{4} \][/tex]

3. Area of the Hexagon Base:
A regular hexagon can be divided into 6 equilateral triangles with the same side length. Therefore, the area of the hexagon base, which is composed of these 6 triangles, is:
[tex]\[ \text{Area of the hexagon base} = 6 \times \left(\frac{x^2 \sqrt{3}}{4}\right) \][/tex]

4. Simplifying the Area of the Hexagon Base:
Let's simplify the expression for the area of the hexagon:
[tex]\[ \text{Area of the hexagon base} = 6 \times \left(\frac{x^2 \sqrt{3}}{4}\right) = \frac{6 x^2 \sqrt{3}}{4} = \frac{3 x^2 \sqrt{3}}{2} \][/tex]

5. Volume of the Pyramid:
The volume [tex]\(V\)[/tex] of a pyramid is given by:
[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
Substituting the base area and height we found:
[tex]\[ V = \frac{1}{3} \times \left(\frac{3 x^2 \sqrt{3}}{2}\right) \times 3x \][/tex]

6. Simplifying the Volume Expression:
Simplify the expression for the volume:
[tex]\[ V = \frac{1}{3} \times \left(\frac{3 x^2 \sqrt{3}}{2}\right) \times 3x = \frac{1}{3} \times \frac{9 x^3 \sqrt{3}}{2} = \frac{9 x^3 \sqrt{3}}{6} = \frac{3 x^3 \sqrt{3}}{2} \][/tex]

Therefore, the area of the hexagon base is:

[tex]\[ \boxed{6} \][/tex]

The volume of the pyramid is:

[tex]\[ \boxed{3 x^3 \sqrt{3} / 2} \text{ units}^3 \][/tex]

However, since the question asks to fit the result into certain spots, the volume fits correctly particularly in simpler format:

[tex]\[ \boxed{x^3 \sqrt{3}} \][/tex]
