The intensity of light that falls on an object is given by the formula I = P/d

In the formula, d is the distance from the light source,

P is the power in lumens, and I is the intensity of light in lumens per square meter.

An object being photographed is 3 meters from a 72-lumen light source.

What is the intensity in lumens per square meter?
