If the force of the explosion was focused onto a smaller of the window, then the pressure of the explosion on the window would be even greater. length area volume density

The correct answer is Area.

Explanation:

Pressure exerted on an object is defined as the ratio of force applied to the surface area.

Mathematically,

Where, p = pressure

F = force applied

a = surface area

From the above relation, pressure is inversely related to area. As, the pressure increases, the area will be small and vice-versa.

So, when force of the explosion was focused on a smaller area, then the the pressure of the explosion on the window was greater.

Hence, the correct answer is Area.
