First, we have to know how to get the volume of a cube.
The volume of a cube is equal to V = s^3.
Given a volume of 1/512, using the formula.
V = s^3
1/512 = s^3
s = cuberoot of 1/512
s = 1/8 meter
7 elements will be compared to find 25 using linear search
<h3>
What is linear search?</h3>
- A linear search, also known as a sequential search, is a technique used in computer science to locate an element inside a list.
- Up until a match is discovered or the entire list has been searched, each element of the list is successively checked.
- In worst-case linear time, a linear search performs at most n comparisons, where n is the length of the list.
- A linear search has an average case of n+1/2 comparisons if each element is equally likely to be searched, but the average case can be impacted if the search probability for each element differ.
- Since other search algorithms and schemes, such the binary search algorithm and hash tables, provide substantially faster searching for all but short lists, linear search is rarely practical.

Using the Pythagorean Theorem, it is found that the base of the pole should be set 10 feet from the end of the wire.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs 
and 
of a right triangle with the length of the hypotenuse h, according to the following equation:
In this problem, the distance is , while the other measures are 
, hence:
The base of the pole should be set 10 feet from the end of the wire.

20+4x=76 subtract 20 from both sides
4x=56 divide both sides by 4
x=14
So he was driving at 55+14=69 mph
