# A math question I've been stuck on.?

Say there is a room of 10m x 10m x 2.3m

You want to paint this room as many times as you can before the room is filled with paint. Assuming each paint layer is 0.0001m and the same thickness everywhere.

How many layers could you paint before the room is completely filled up?

(Also I know you'd have to be able to stand in the room to paint it but the case I've laid out here is purely hypothetical.)

The smallest dimension is 2.3m (height?). Each coat will cover 0.0002m (both sides).

2.3 / 0.0002 = 11,500 coats.
