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$

deff fn [24]

Answer:

There's a picture pf ratio tables below if you would like to view that.

Step-by-step explanation:

Let me explain this table to you. So in the first part. 1 group has 5 apples in it. Second group has ten. If you look the pattern you can tell that the groups are always multiplied by 5. 1 x 5 equals to 5. 2 x 5 equals 10. 4 x 5 equals 20 and so on. at the very end it's 135 times 5 equals 160. So there ya go for the ratio tables. I really hope this helps you. (times 5 is the ratio)
