Question

How tall is a stack of ten pennies in centimeters?

Answer 1

we know that

The Penny is the one cent coin of the United States.The coin is 19.05 millimeters in diameter and 1.52 millimeters thick.

So

the height of a stack of ten pennies is equal to

$10*1.52=15.2 mm$

to convert mm to cm divide by $10$

$\frac{15.2}{10} =1.52cm$

therefore

the answer is

$1.52 cm$

Answer 2

A penny is 1.52 mm, so 10 pennies are 15.2 mm. 15.2 mm=1.52 cm
So a stack of 10 pennies is 1.52 centimeters<span />
