I know that the difference between two
consecutive numbers squared is the sum of
those consecutive numbers.
The two consecutive numbers, whose squares differ by 55, are 13 and 12.
I realized that the greatest number of boxes
is the greatest common factor of all three
numbers.
I used the table method to find the GCF.
The final set of numbers, 12, 10, and 9,
represent the quotient for each amount
when divided by the GCF. That means 12,
10, and 9 are the amount of each item to be
packed in each box.
The greatest number of boxes is 12 boxes. Riley can pack 12 pencils, 10
files, and 9 notebooks into each box.
I used a chart to find the least common
multiple because I need to find how
much time would go by before they
were all at the same place.
Imelda, Susan, and Clara will meet again in 630 minutes or 10 hours and 30
minutes.
5 squares will cover one row of
The 30 inch square. You need to
square the 5 to find out how many
5-inch squares cover the area.
You would need to use 25 6-inch squares to cover a 30-inch square.
This problem is similar to 34, but it is a
cube instead of a square. You find out
how many cube create one row of the
cube, but this time, to find the number of
cubes that fill the larger cube, you need
to cube the 6.
You would need to use 216 6-inch squares to cover a 30-inch square.
