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
MAXImum [283]

Answer:

(A)The height of each pyramid is One-half h units.

Step-by-step explanation:

Height of the Cube = h units

Volume of the Cube =h^3 $ cubic units

If Base of the cube =Base of the square pyramid

Base of the square pyramid = h units

\text{Volume of a Pyramid}=\dfrac{1}{3}*Base Area*Height

\text{Volume of One Pyramid}=\dfrac{1}{3}*h^2*Height

\text{Volume of Six Pyramids}=6*\dfrac{1}{3}*h^2*Height\\=(2h^2*Height)\:cubic\:units

Since Volume of the Cube = Volume of Six Square Pyramids

Then:

2h^2*Height=h^3\\Height=\dfrac{h^3}{2h^2} \\$Height of each pyramid =\dfrac{1}{2}h \:Units

Calculate the volume of the following figure.
Leni [432]

Answer:

  • \boxed{\sf{24\ units\ ^3}}

Step-by-step explanation:

In order to solve this, you must use the volume of the cube.

\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}

\Longrightarrow: \sf{V=L*W*H}

  • L: (length) = 3
  • W: (width) = 2
  • H: (height) = 4

<u>Multiply.</u>

<u />

<u>Use the order of operations.</u>

<u>PEMDAS stands for:</u>

  • <u>Parentheses</u>
  • <u>Exponents</u>
  • <u>Multiply</u>
  • <u>Divide</u>
  • <u>Add</u>
  • <u>Subtract</u>

\Longrightarrow: \sf{3*2*4}

<u>First, do multiply. </u>

\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}

  • <u>Therefore, the volume of the cube is 24 units³, which is our answer.</u>

I hope this helps. Let me know if you have any questions.
