Answer:
18 kilometers
Step-by-step explanation:
If each 1 cm represents 9 kilometers.
How many would 2 cm represent?
![x = \frac{9 \times 2}{1} = 9 \times 2 = 18](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B9%20%5Ctimes%202%7D%7B1%7D%20%20%3D%209%20%20%5Ctimes%202%20%3D%2018)
It's hard to explain, but theres a trick to it too.
Answer: 3 ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Follow the radical rule:
=
We get the number
Follow the exponent rule:
=
We get the number
.
Now, subtract.
![= \frac{2}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2%7D%7B3%7D)
The answer is 3 2/3
Answer:

Step-by-step explanation:
<u>Answer:</u>
The volume of a pyramid is ![2406.16 cm^3](https://tex.z-dn.net/?f=2406.16%20cm%5E3)
<u>Explanation:</u>
We know that volume of a square based pyramid is given by the formula,
![\mathrm{V}=\mathrm{a}^{2} \frac{h}{3}](https://tex.z-dn.net/?f=%5Cmathrm%7BV%7D%3D%5Cmathrm%7Ba%7D%5E%7B2%7D%20%5Cfrac%7Bh%7D%7B3%7D)
where V = Volume
a = base length = 17.2cm (given)
And h = height of the pyramid = 24.4cm
So,
![V=17.2^{2} \frac{24.4}{3}](https://tex.z-dn.net/?f=V%3D17.2%5E%7B2%7D%20%5Cfrac%7B24.4%7D%7B3%7D)
=>
which is the volume of the given pyramid .
