Admission test for the degree course in medicine and surgery 2012-2013

Domanda 3 di 80

I wish to repaint the walls of my garage. It is 3 metres high, 4 metres wide and 9 metres deep. I shall not need to paint the electronic door which covers one 3 x 4 metre end, nor the window, which is 2 metres wide and 1 metre high, nor the rear door which is 1 metre wide and 2 metres high. 1 litre of paint covers 3 square metres. How many 1 litre tins will be needed to complete the painting?
