The pressure exerted by weight of a cubical block of side 3cm on the surface is 5 Pa. Calculate the weight (or force) of the block.

Explanation

To solve the problem, we need to find the weight (or force) of a cubical block given the pressure it exerts on a surface. Here’s a step-by-step solution:

### Step 1: Understand the given information
We are given:
- The side length of the cubical block = 3 cm
- The pressure exerted by the block on the surface = 5 Pa

### Step 2: Convert the side length from centimeters to meters
