Answer:
Scale factor = ![\frac{4}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D)
Perimeter ratio = 4 : 9
Surface area ratio = 16 : 81
Volume ratio = 64 : 729
Step-by-step explanation:
Volume ratio = ![\frac{\text{volume of small prism}}{\text{Volume of large prism}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bvolume%20of%20small%20prism%7D%7D%7B%5Ctext%7BVolume%20of%20large%20prism%7D%7D)
= ![\frac{128}{1458}](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B1458%7D)
=
= 64 : 729
Scale factor = ![\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B%5Ctext%7Bvolume%20of%20small%20prism%7D%7D%7B%5Ctext%7BVolume%20of%20large%20prism%7D%7D%7D)
= ![\sqrt[3]{\frac{64}{729}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B64%7D%7B729%7D%7D)
= ![\frac{4}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D)
Perimeter ratio = Scale factor
= ![\frac{4}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B9%7D)
= 4 : 9
Surface area ratio = (Scale factor)²
= ![(\frac{4}{9})^{2}](https://tex.z-dn.net/?f=%28%5Cfrac%7B4%7D%7B9%7D%29%5E%7B2%7D)
= ![\frac{16}{81}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B81%7D)
= 16 : 81
You just solve it like a normal multiplication problem and then start putting the decimal begin the answer and place it 3 numbers forward
