An illustration shows a hexagonal prism with the label Choosy Cheesy on the top surface. The height of the hexagonal prism is 8 centimeters. The two longer parallel sides of the hexagonal prism each measure 30 centimeters in length. One end of the prism is marked with a dashed line measuring 15 centimeters across, joining the two opposite vertices of the parallel edges, forming a triangular prism with a perpendicular measure of 8 centimeters.

A sample of gourmet cheeses came in this box. What is the volume of the box?

To find the volume of the box, we need to find the volume of both the hexagonal prism and the triangular prism and then add them together.

Volume of hexagonal prism:
Area of base = 1/2 * (3√3 * s^2), where s is the length of one side of the hexagon. Since the longer sides are 30 cm, s = 30/2 = 15 cm.
Area of base = 1/2 * (3√3 * 15^2) = 1/2 * 3√3 * 225 = 337.5√3 cm^2

Volume = base area * height = 337.5√3 * 8 = 2700√3 cm^3

Volume of the triangular prism:
Volume = base area * height = 1/2 * b * h * height = 1/2 * 15 * 8 * 8 = 480 cm^3

Total volume of the box = Volume of hexagonal prism + Volume of triangular prism
Total volume = 2700√3 + 480 ≈ 2001.06 cm^3

Therefore, the volume of the box is approximately 2001.06 cm^3.

I apologize for the error in my previous calculation. Let's correct it:

Volume of hexagonal prism:
Area of base = (3√3 * s^2/2), where s is the length of one side of the hexagon. Since the longer sides are 30 cm, s = 15 cm.
Area of base = (3√3 * 15^2/2) = (3√3 * 225/2) = (337.5√3) cm^2

Volume = base area * height = (337.5√3) * 8 = 2700√3 cm^3

Volume of triangular prism:
Volume = base area * height = (1/2 * 15 * 8) * 15 = 900 cm^3

Total volume of the box = Volume of hexagonal prism + Volume of triangular prism
Total volume = 2700√3 + 900 ≈ 3192.58 cm^3

Therefore, the correct volume of the box is approximately 3192.58 cm^3.

Let's recalculate the volume of the box:

Hexagonal prism:
Area of base = 3√3 *(side length)^2 / 2 = 3√3 * 15^2 / 2 = 3√3 * 225 / 2 = 337.5√3 cm^2
Volume = base area * height = 337.5√3 * 8 = 2700√3 cm^3

Triangular prism:
Base area = 1/2 * base * height = 1/2 * 15 * 8 = 60 cm^2
Volume = base area * height = 60 * 15 = 900 cm^3

Total volume of the box = Volume of hexagonal prism + Volume of triangular prism
Total volume = 2700√3 + 900 = 3600 + 900√3 = approximately 4560 cm^3

Therefore, the correct volume of the box is approximately 4560 cm^3. Thank you for pointing out the error.
