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.

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parab
salantis [7]

I would not normally stop to answer this question, mainly because
there is no question asked.  It's just three statements.

I do have to stop here and leave a remark, however. 

Math and Physics are closely enough related that I would not
have expected to see what I see here.  Although the math in
this question is reasonable, the Physics is inexcusable.

A rainbow is always a part of a circle.
Rainbows are never parabolas.

You could never cut a parabola out of paper, and then
hold it up in front of you after a rainstorm, and match it
to the rainbow.
