Answer:
C. 4
Explanation:
We have been given an image of two similar prisms. We are asked to find the value of x.
Since both prisms are similar, so we will use proportions to solve for x as corresponding sides of similar figures are proportional.
We can see that side with measure 1 unit corresponds to x and side with measure 24 units corresponds to side that measure 6 units. So we can set an equation as:

Let us solve for x.


Therefore, the value of x is 4 units and option C is the correct choice.
