Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³
You can write 2311 and 3912 in the form
:


Then


Taken modulo 20, the terms containing powers of 20 vanish and you're left with

We further have

so we end up with

and so
.
###
If instead you're trying to find
, you can apply Euler's theorem. We can show that
using the Euclidean algorithm. Then since
, and 8 divides 3912, we have

To show 2311 and 20 are coprime:
2311 = 115*20 + 11
20 = 1*11 + 9
11 = 1*9 + 2
9 = 4*2 + 1 => gcd(2311, 20) = 1

Hey!
-------------------------------------------------
Solution:
~10 can go in to 25 two times.
10 + 10 = 20
25 - 20 = 5 (remainder)
~20 means that the whole number is 2.
2 5/10
~Simplify and Answer
2 1/2 or 2.5
