As a gravestone or grave marker is an integral part of a cemetery, most ... add about an inch more on each side to leave some margin for ground setting. 

Traditional in-ground burials involve the body of the deceased being interned into a casket. The casket is then placed into a vault or outer burial container, in an excavation, where it is covered with soil.  

It can be placed in a columbarium or mausoleum, or buried in the ground. Vault: A grave liner that completely encloses a casket. 

A scattering garden is a beautifully decorated area with the express purpose of having ashes scattered upon it, providing a natural, eternal fertilizer for the flowers and plants, and serving as a cemetery of sorts for those who wish to be cremated but for whom loved ones still want a tranquil and solemn setting to visit.
