If each light fixture on a job requires 4 lamps and each room requires 16 fixtures, how many lamps will be required for 6 rooms?

384 lamps

Step-by-step explanation:

This is simply a multiplication problem. From the question, we know that each fixture needs 4 lamps with a single room needing 16 fixtures.

The number of lamps required by each room is thus 16 * 4 = 64 lamps

Now, the total number of lamps required by 6 rooms is thus 64 * 6 = 384 lamps
