Magnification is equal to image size divided by the actual size, or M = I/A.
The image size is the student's drawing, which is 28.8 cm, and the actual size is 7.2 cm. Divide them, and cancel out the units, and you should get:
28.8 cm/7.2 cm = 4

Explanation:
From the question we are told that
The position of the column of mercury in the barometer is \
The density of mercury is
Generally the pressure of the atmosphere at that column is mathematically represented as
=>
=>
Generally the atmospheric pressure at sea level (Generally the pressure before the change in level of the mercury column) is
Generally the change in air pressure is mathematically represented as
=>
=>
Generally the height which the column will rise to is mathematically evaluated as
Here is the density of water with value
So
=>
