Final answer:
The slightly oversize casket may or may not fit in a standard vault, depending on the dimensions of the vault.
Step-by-step explanation:
The size of the casket in question is 32 inches wide and 84 inches long. To determine if it will fit in a standard vault, we need to compare the dimensions of the casket to the dimensions of the vault. Unfortunately, the information provided does not include the dimensions of a standard vault. Therefore, without that information, we cannot determine if the slightly oversize casket will fit in a standard vault.
