Question from Georgia, a student:

I have been given the following question in a maths assingment, and have so far been unable to answer it.

To begin, i am required to draw a square pyramid as follows:

1. draw a 3 dimensional diagram of a square based pyramid

2. label the square base as ABCD, call the vertex H.

3. Mark in E and F the midpoints of AD and BC respectively and O is the midpoint of EF

Note: this therefore makes FO = FC

this i was fine with, it was the following question that stumped me.

1. if the height of the pyramid is 280m, what is the length of the base?

Thanks, Georgia
