Question

Jensen is building a snow fort. Each block in the fort weighs about 1 kilogram. Jensen hopes to make about 40 blocks for the fort. If a snowflake weighs about 3 • 10 ^-3 grams, approximately how many snowflakes will be in the fort.

Answer 1

Answer: 13,333 snowflakes

Explanation:

For this exercise let be "x" represents the number of snowflakes that will be in the fort.

According to the information given in the exercise, the weight of one block is 1 kilogram. Knowing that the fort must have 40 blocks, the total weight is:

`total\ weight=(1\ g)(40)\\\\total\ weight=40\ g`

Since each snowflake weighs
`3* 10^(-3)` grams, need to divide the total weight calculated above by the weight of a snowfake.

Therefore, through this procedure you get the following result:

`x=(40\ grams)/(3 * 10 ^(-3)\ grams)\\\\x\approx13,333`

Therefore, the there will be 13,333 snowflakes in the fort.
