Understanding the Problem

When constructing a toy pyramid, the goal is to use the maximum amount of material to cover the sides and bottom of the pyramid. This problem can be approached using mathematical concepts, specifically geometry and optimization. In this article, we will delve into the world of mathematics to find the correct answer to the question: what is the height of the toy pyramid?

The Geometry of a Pyramid

A pyramid is a three-dimensional shape with a polygonal base and triangular sides that meet at the apex. The base of the pyramid is a square with side length 's', and the height of the pyramid is 'h'. The slant height of the pyramid, which is the distance from the apex to the midpoint of one of the sides of the base, is given by the Pythagorean theorem as √(h² + (s/2)²).

Calculating the Surface Area

The surface area of the pyramid consists of the area of the base and the area of the four triangular sides. The area of the base is simply s², and the area of each triangular side is (1/2) × s × √(h² + (s/2)²). Therefore, the total surface area of the pyramid is:

s² + 4 × (1/2) × s × √(h² + (s/2)²)

Optimizing the Surface Area

To maximize the surface area, we need to find the value of 'h' that maximizes the expression:

s² + 4 × (1/2) × s × √(h² + (s/2)²)

This is a complex optimization problem, and we can use calculus to find the maximum value. However, we can also use a simpler approach by recognizing that the surface area is maximized when the slant height is equal to the height of the pyramid. This occurs when:

h = √(h² + (s/2)²)

Squaring both sides and simplifying, we get:

h² = (s/2)²

h = s/2

The Correct Answer

Therefore, the height of the toy pyramid is s/2.

Conclusion

In this article, we explored the problem of optimizing the material for a toy pyramid. We used mathematical concepts, specifically geometry and optimization, to find the correct answer to the question: what is the height of the toy pyramid? The answer is s/2, which is a simple yet elegant solution to a complex problem.
