if each sphere has a mass of 120 gms,what is the massof a pyramid?

We have no idea of the relationship between the spheres and the pyramid.

To determine the mass of a pyramid, we need additional information, such as the number of spheres that make up the pyramid and their arrangement.

Please provide more details about the pyramid's structure or any other relevant information.

To determine the mass of a pyramid, we need more information. The mass of each sphere (120 g) is not sufficient to calculate the mass of the entire pyramid. In order to find the total mass of the pyramid, we need to know the number of spheres in the pyramid and the weight distribution.

If you provide additional details, such as the number of spheres in the pyramid or the weight distribution (e.g., all spheres are equally spaced and positioned), I can help you calculate the mass of the pyramid.
