Here we go !!
Since it's a regular pentagon, all it's sides are equal so let's solve for x






now let's find the measure of each side, i.e





perimeter = 5 × side length ( for a regular pentagon )


Representing 3 and one tenth as decimal by 3.1
<u>Step-by-step explanation:</u>

Answer:
Step-by-step explanation:
We know that
scale factor=1/4
so
volume of the smaller pyramid=[scale factor]³*volume original pyramid
volume original pyramid=192 unit³
volume of the smaller pyramid=[1/4]³*192---> (1/64)*192----> 3 units ³
the answer is
3 units³
