Is it bigger than a bread box??
We need something for size referance.

But the looks of it I would say Fire Nugget / melted aluminum can.

If you can you should test the density. Divide the weight in grams by the volume in milliliters and you'll get the density in grams per cubic centimeter. It looks like Aluminum, but knowing the density could help verify.

How do I find the volume?

Eureka!

When people exclaim Eureka! they are reenacting a legendary event in the life of the Greek mathematician and inventor Archimedes. While wrestling with the problem of how to determine the purity of gold, he made the sudden realization that the buoyancy of an object placed in water is equal in magnitude to the weight of the water the object displaces. According to one popular version of the legend, he made his discovery at a public bathhouse, whereupon he leapt out of his bath, exclaimed “Heureka! Heureka!” (“I have found it!”), and ran home naked through the streets. The absence of a contemporary source for this anecdote has done nothing to diminish its popularity over the centuries.

How do I find the volume?

if you have a small measuring cup or beaker, put a set amount of water in it and then drop your object in the water. However much it displaces is the volume of your object.

if you have a small measuring cup or beaker, put a set amount of water in it (say ten milliliters) and then drop your object in the water. However much it displaces is the volume of your object.

Thank you.
