Answer:

A rectangle

Step-by-step explanation:

If you were to take a rectangle a put it on to a 3 dimensional coordinate plane, you can put one entire side against an axis (lets use the y axis for example). Take the long side of a rectangle, rotate it along the y axis, and you get a 3 dimensional cylinder.

Answer:

40 socks

Step-by-step explanation:

There are 48 socks in total inside the drawer. 2 pairs of white socks means four white socks. The worst possible scenario (however unlikely it is) is that Laura takes all of the red, blue and green socks before picking any white sock. From that point on, Laura has to pick four more socks in order to have two white pairs. In this scenario, there are 8 socks left in the drawer, all white. Therefore, the minimum number of socks that Laura must take to be sure that she has two pairs of white socks is:

$n=(12*4) - 8\\n=40\ socks$
