Answer
128 bytes
Reason — The given table represents a 4×4 two-dimensional array (4 rows and 4 columns), which means there are 16 elements in total. The values include both integers and decimal numbers, indicating that the array is of double data type (which can store both whole numbers and decimal numbers).
In Java, a double occupies 8 bytes.
So, total bytes = 16 elements × 8 bytes = 128 bytes.
