Can you show me how to work this problem.

Question

a building is 1.2 x 10^5 millimeters tall.

has 28 floors. How tall is each foot. Do I add or multiply?

Answer 1

I think you meant to ask "How tall is each FLOOR?"

 

You DIVIDE the height of the building by the number of floors to get the height of each floor, assuming they all have the same height.

 

h = (1.2 x 10⁵ mm) / 28 = ?
