I believe it is positive so option 2
It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
First, we are going to find the scaling factor of the volume, and then, we are going to multiply that scaling factor by the volume of the smaller prism.
We know that our hexagonal prism <span>has dimensions that are triple the dimensions of a similar smaller hexagonal prism. The scaling factor for each dimension is 3, but since we have 3 dimension (a prism is a 3 dimensional figure), we need to rise that scaling factor to the power 3 (that represent the three dimensions of our prism):
</span>

<span>
Now we just need to multiply our volume scaling factor by the volume of our smaller prism:
</span>


<span>
We can conclude that the correct answer is the fourth choice: </span><span>
