Step-by-step explanation:
Using the density formula:
.....[1]
As per the statement:
If the volume of a cube of wood is 15.625 cm3 and its mass is 10.00 grams.
⇒Volume = 15.625 cubic cm and mass = 10 gram
Substitute the given values in [1] we have;

Simplify:
density = 0.64

Therefore, the density of the wood is, 0.64
