Answer:
D) 45 ft
Step-by-step explanation:
The two triangles are shown below.
Given:
BC = 60 ft, CD = 24 ft and DE = 18 ft.
Since, the two triangles are similar, their corresponding sides are in proportion.
So, 
Now, consider the proportion of sides,

Therefore, the distance between A and B is 45 ft.

<h2>
Step-by-step explanation:</h2>
A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. On the other hand, a rectangular prism is a solid whose base is a rectangle. Multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:

From the statement of the problem we know:

So:

Since we can't have negative distance, the only valid option is
