rachel has two hexagonally shaped birthday cakes, the smaller of which serves six people. If the length of one side of the larger cake is twice that of the smaller cake how many people does the larger cake serve ???

the bigger cake has a length twice that of the small one, that means that linear factor is 2.

from the definations:

area factor= (linear factor)^2

volume factor=(linear factor)^3

therefore to find the area factor then;

area factor=(linear factor)^2

area factor=(2)^2

area factor=4

hence the bigger cake serves (6*4) people

=24 people
