You can convert 1000 to hex and see how many digits that requires:
So every integer below 1000 needs up to 3 digits.
Alternatively, we know that
, and that 
requires 
digits in its hex representation (e.g. 
). Taking the logarithm, we get 
, and adding 1 gives the number of digits needed to represent 
. Similarly,
So every integer below 1000 needs up to 3 digits.
Alternatively, we know that
Answer:
10 feet
Step-by-step explanation:
Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is
.
Ratio of the height is then .
At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.
