Question

Ben says that an array with 2 rows and 5 columns has 8 items. Is this reasonable? Explain why or why not

Answer 1

Answer:

Incorrect

Step-by-step explanation:

Consider an array  with 2 rows and 5 columns.

Each row contains 5 elements (one element per column).

Thus, two rows contain

$5 +5=10$

elements.

Therefore, Ben is incorrect.

In general, the array with m rows and n columns cotains

$m\cdot n$

elements.
