Question

a grain of sand has a diameter that is 60 μm long. under a microscope, it looks 48,000 μm long. what magnification scale was used? hint: scale factor = scaled image dimension / original dimension 800 8,000 80 400

Explanation:

Step1: Identify values

Scaled image dimension = 48000 μm, Original dimension = 60 μm

Step2: Apply scale - factor formula

Scale factor = $\frac{Scaled\ Image\ Dimension}{Original\ Dimension}=\frac{48000}{60}$

Step3: Calculate the result

$\frac{48000}{60}=800$

Answer:

800
