Answer:

The correct answer is -

1. 1 grain of sand = 244 red blood cells.

2. 1 penny = 2439

Explanation:

A normal red blood cell has a normal disk diameter of 6.2 - 8.2 micron or micrometer is way small than a grain of sand which ranges in diameter from 0.0625 mm (or ​1⁄16 mm) to 2 mm. The size of the diameter of a penny is given 0.02 m.

Let take the highest value of them:

RBC = 8.2 micrometer

The grain of sand = 2 mm

Penny = 0.02 m

we know:

1 meter = 10e+6 or 100000 micron

1 millimeter = 1000 micron

then, the grain of sand = 2* 1000 = 2000

so, the 1 grain sand = 2000/8.2

= 244

Similarly,

Penny = 0.02*100000= 20000

= 2439

Thus, the correct answer is =

1. 1 grain of sand = 244 red blood cells.

2. 1 penny = 2439
