Answer:

x = \frac{19+\sqrt{365}}{2}, \frac{19-\sqrt{365}}{2}

Step-by-step explanation:

1. Move everything to one side of the equation.

x^2 - 19x - 1 = 0

2. Use the quadratic formula where a = 1, b = -19, and c = -1.

x = (-b +- sqrt(b^2-4ac)) / 2a

If you plug those numbers into that formula, you will get the result listed above

Six pyramids are shown inside of a cube. The height of the cube is h units. Six identical square pyramids can fill the same volu
Amiraneli [1.4K]

The height of squared pyramid is \frac{1}{3}h unit.

<h3>What is the volume of a cube?</h3>

A cube is a solid three-dimensional object with six square faces or sides, three of which meet at each vertex. One of the five Platonic solids, the cube is the only regular hexahedron. It contains 8 vertices, 6 faces, and 12 edges.

Volume of cube = (side)^3 \ unit^3

Given the height of cube is h unit.

Volume of cube is h^3 \ unit^3

Let the height of squared pyramid is x unit

Volume of squared pyramid is \frac{1}{3} h^{2} \times x \ unit^3

According to the question, we have

Volume of cube = 6 \times volume of squared pyramid

\Rightarrow h^3=6 \times \frac{1}{3}h^2 \times x\\\Rightarrow h^3=2 \ h^2 \times x\\\Rightarrow h=2x\\\Rightarrow x= \frac{1}{2}h

Therefore, the height of squared pyramid is \frac{1}{3}h unit.
