How many cubic cm of iron is required to construct open box whose external dimensions are 36 cm 25 cm and 16.5 cm provided the thickness of the iron is 1.5 cm lf one cubic cm of iron weights 7.5 gm then find the weight of the box.

Explanation

To solve the problem step by step, we will find the volume of iron required to construct the open box and then calculate its weight.

### Step 1: Find the external dimensions of the box.
The external dimensions of the box are given as:
- Length (L) = 36 cm
- Width (W) = 25 cm
- Height (H) = 16.5 cm
