It is assumed the base of the prism is a square wit side of 5 cm.
<u>The volume is:</u>
<u>The base is:</u>
<u>Find h:</u>
Probaility in general is defined as the ratio of positive outcomes over the total number of outcomes.
In the first example, the total outcomes are 16; let us count the positive ones. There are 8 even numbers from 1-16. The prime numbers are 2,3,5,7,11,13. Out of those, only 5 are odd. Hence, in total there are 13 positive outcomes. Thus, the probability is 13/16=81.25%
Let's restrict the problem to the students that studied for the exam; the proportion is 0.57 of the total students. 0.52 of the total students studied and saw an increase in their exam. Hence, the probability that a student who studied saw an increse is 0.52/0.57 (here a positive outcome is the proportion that saw an increase and the total outcomes are all the students that studied). 0.52/0.57=91.22%

Answer:
the first one hunz
Step-by-step explanation:
The volume of a prism is given by
Where 
is the base are and 
is the height.
So, if two prisms have the same height and the same volume, they must have the same base area.
The first base is an equilateral triangle, which means that the height is given by
So, the area is
The area of the second base is simply the product of the dimensions, so it is 
Since the two areas must be the same, we have
