Math Problem Statement

his ornate box is in the shape of a regular hexagon. The length of each edge is nine and a half centimetres. The distance across the box from the middle of one edge to the middle of the opposite edge is 17cm. What is the area (to two decimal places) of the base of the box in square centimetres?

Solution

To find the area of the base of the hexagonal box, we use the formula for the area of a regular hexagon:

A=332s2A = \frac{3\sqrt{3}}{2} s^2

where ss is the side length of the hexagon.

Step 1: Substitute s=9.5s = 9.5 cm

A=332(9.5)2A = \frac{3\sqrt{3}}{2} (9.5)^2

Step 2: Compute s2s^2

9.52=90.259.5^2 = 90.25

Step 3: Multiply by 332\frac{3\sqrt{3}}{2}

Approximating 31.732\sqrt{3} \approx 1.732:

3×1.7322=5.1962=2.598\frac{3 \times 1.732}{2} = \frac{5.196}{2} = 2.598

A2.598×90.25A \approx 2.598 \times 90.25

A234.43 cm2A \approx 234.43 \text{ cm}^2

Final Answer:

234.43 cm2\mathbf{234.43 \text{ cm}^2}

Tip:

For any regular hexagon, you can also calculate the area using the formula:
A=12×perimeter×apothemA = \frac{1}{2} \times \text{perimeter} \times \text{apothem}
where the apothem is given as half the distance across opposite edges.
