Intensity and power (photon picture)

The intensity of light falling on a $20{\text{cm}}^2$‍ area of a wall is $5\times {10}^3{\displaystyle \frac{\text{W}}{{\text{m}}^2}}$‍. The frequency of the light source is $5\times {10}^{14}\text{Hz}$‍.

Find the number of photons that hit the area in $2.0\text{s}$‍.$\begin{array}{rl}& \\ & \end{array}$‍ Note: Take $h=6.6\times {10}^{-34}\text{J s}$‍ and round-off your answer to one decimal place.
