Answer:
The area of the base of the pyramid is 109.2 mm.
Step-by-step explanation:
The area of the base of a hexagonal pyramid is given by the area of a hexagon:
[tex] A_{b} = \frac{P*a}{2} [/tex]
Where:
P: is the perimeter
a: is the apothem
We need to find the perimeter and the apothem.
The perimeter is equal to:
[tex] P = 6*s [/tex]
Where:
s: is the side of the pyramid
And the apothem is:
[tex] a = \frac{\sqrt{3}}{2}*s [/tex]
So, to calculate the apothem and the perimeter we need to calculate the side of the pyramid. We can find it from the volume of the pyramid:
[tex] V = \frac{\sqrt{3}}{2}*h*s^{2} [/tex]
Where:
h: is the height = 4 mm
V: is the volume = 144 mm³
Then, the side is:
[tex] s = \sqrt{\frac{2V}{\sqrt{3}*h}} = \sqrt{\frac{2*144}{\sqrt{3}*4}} = 6.5 mm [/tex]
Now, we can find the perimeter and the apothem.
[tex] a = \frac{\sqrt{3}}{2}*s = \frac{\sqrt{3}}{2}*6.5 = 5.6 mm [/tex]
[tex] P = 6*s = 6*6.5 = 39 mm [/tex]
Finally, the area is:
[tex] A_{b} = \frac{P*a}{2} = \frac{39*5.6}{2} = 109.2 mm^{2} [/tex]
Therefore, the area of the base of the pyramid is around 109 mm.
I hope it helps you!
ah im having a hard time with this someone answer plz no one is answering the question exept bots trying to scam me.an online retailer charges $5.99 plus 0.65 per pound to ship to electronics purchases.How many pounds is a ... for which the shipping charge is $22.89. ive been having a bit of trouble finding this out,much appretiation if you solve this.Thanks!
Answer:
26 pounds
Step-by-step explanation:
let x be the number of pounds.
then
5.99+0.65x=22.89
0.65 x=22.89-5.99=16.90
[tex]x=\frac{16.90}{0.65}=\frac{1690}{65}=26\\[/tex]

The large solid below is made from small cubes. Each has a side length of 1/4.
Answer the questions below. Write your answers in simplest form.
(c) What is the volume of the large solid?
Answer:
A is 36 small cubes, because by looking at the image, you can see 3 rows of cubes containing 6 cubes each. So that would be 3 times 6, which is 18. There are 2 of these arrangements, one on top and the other on the bottom. So we multiply 18 by 2 to get 36 small cubes.
B is 1/64ft cubed, because the volume of a cube is length x width x height, and because each is the same (it is a cube) we take the length of the cube (1/8) and multiply it 2 times, to get 1/8 x 1/8 x 1/8 = 1/64 cubic feet.
C is 9/16 cubic feet for the volume of the entire cube. Because we know that there are 36 small cubes total, and we know that each cube is 1/64 cubic foot in volume, we multiply 36 small cubes, by their volume, 1/64 feet cubed to get the fraction of 9/16 .
Step-by-step explanation:
Answer:
3/4 x 6/4 x 2/4
Step-by-step explanation:
You need to multiply length * width * height to find volume.
Since each cube is 1/4, we have to multiply 3 for the width.
3 x 1/4 = 3/4.
Since there are 6 cubes for the length, you have to multiply 6 x 1/4 = 6/4
Finally, since the height is 2 cubes, you have to do 2 x 1/4 = 2/4
Finally, you multiply them all.
3/4 x 6/4 x 2/4
