Question

A box of staples contains 6 x 103 staples and weighs 12 oz. How much does one staple

weigh? Write your answer in scientific notation. Round your answer to the nearest tenth, if
necessary.

Answer 1

2 * 10^-3 oz

Explanation:

Given that:

Number of staples per box = 6 * 10^3

Weight of staple box = 12 oz

Weight per staple = (weight of staple box / number of staples per box)

Weight per staple = 12 / 6 * 10^3

Weight per staple = 12 / 6 * 1000

= 12 / 6000

= 0.002 oz

= 2 * 10^-3 oz
