Answer:
5.38 ounces
Step-by-step explanation:
Given that :
Alice height = 1 mile
Distance of earth to moon = 239000 miles
Number of base 10 cakes required so they Alice's head just touches the moon ;
Using the relation :
Distance = height per ounce * 10^number of ounces
Height per ounce = 1 mile ;
Let number of ounces = n
Hence,
239000 = 1 * 10^n
239000 = 10^n
Take log of both sides
Log(239000) = n
5.3783979 = n
5.3784 = n
Hence, Alice should take 5.38 ounces of base 10 cakes
