Question

A new exhibit at the museum focuses on skin, the body's largest organ! It differs in thickness all over your body. The soles of your feet are the thickest, at 1 2/5 millimeters. Your eyelids are the thinnest, just 1/70 times the thickness of your soles. How thick is the skin on your eyelids? Express your answer as a decimal.

Answer 1

0.02 mm

Explanation:

Let's convert the numbers given in decimal first, for ease of calculation.

Thickness of soles of feet = 1 2/5th mm, which is 1.4 mm

THick ness of eyelids are 1/70 TIMES the thickness of soles

So we multiply 1/70 [in decimal that is 0.0143 (rounded to 4 decimals) ] with 1.4:

0.0143 * 1.4 = 0.02 mm

So, the thickness of skin on your eyelids is 0.02 mm
