Answer / Sabiha

To calculate the volume of a random rubble masonry with given dimensions, we need to consider the void ratio (air spaces between stones) and the density of the stone material. However, without specific values for these variables, it's not possible to provide an accurate estimate.

Generally, a typical void ratio for random rubble is around 40-60%. To calculate the volume V of the masonry, you can use the formula:

V = L * H * (1 - void_ratio)

Where:
- L is the length (1 km in this case)
- H is the height (0.9 m)
- void_ratio is the void ratio (assuming 50% as an example)
