Question

Harvey Porter is a wizard. He made a grain of sand grow from a diameter of 0.00002 m to a diameter of 0.006 m. Approximately, how many times as large is the diameter of the grain of sand now as it was before Harvey Porter waved his wand?

Answer 1

The diameter of the grain of sand increased from 0.00002 m to 0.006 m, making it approximately 300 times larger than it was originally.

Step-by-step explanation:

The question is asking how many times larger the diameter of a grain of sand is after a wizard named Harvey Porter has enlarged it. Originally, the grain of sand had a diameter of 0.00002 m and it increased to a diameter of 0.006 m.

To find out how many times larger the new diameter is compared to the original, we divide the new diameter by the original diameter:

0.006 m / 0.00002 m = 300 times larger.

Therefore, the diameter of the grain of sand is now approximately 300 times as large as it was before Harvey Porter waved his wand.
