Each page of a top-secret report on aliens requires 8KB of space in digital format.

What is the maximum number of pages the report can have so that it can be completely stored on a 2GB usb drive?

Write your answer in scientific notation, and round to one decimal place.

For reference, 1GB= 10^6 KB

2GB x 10^6=2 x 10^6 KB

[2 x 10^6] / 8 =250,000 =2.5 x 10^5 pages-the maximum number that the USB Drive can hold.

\(2GB=2\times10^6KB\)

\(\quad Maximum\space Number\space of\space Pages \\ =\frac{2\times10^6}{8}\\=\frac{10\times10^5}{4}\\=2.5\times10^5\\=0.25\times10^6\)

Round the number by yourself. Trust me, it's easy.
