For each pyramid option, calculate the total number of shoeboxes used after each row has been completed. That is calculate the total number of shoeboxes in the top row, the total number of shoeboxes in the top three rows, and so on.
Please help me i'm very confused!
`Please and Thanks!
Sure, I can help you with that. To calculate the total number of shoeboxes used after each row has been completed for each pyramid option, we need to find the sum of the shoeboxes in each row.
Option 1:
In the first row, we have 2 by 3 shoeboxes, which means 6 shoeboxes.
In the second row, we have 3 by 4 shoeboxes, which means 12 shoeboxes.
In the third row, we have 4 by 5 shoeboxes, which means 20 shoeboxes.
To calculate the total number of shoeboxes in the top row, we add up the shoeboxes in each row:
Top row: 6 shoeboxes
Top three rows: 6 + 12 = 18 shoeboxes
All rows: 6 + 12 + 20 = 38 shoeboxes
Option 2:
In the first row, we have 2 by 2 shoeboxes, which means 4 shoeboxes.
In the second row, we have 3 by 3 shoeboxes, which means 9 shoeboxes.
In the third row, we have 4 by 4 shoeboxes, which means 16 shoeboxes.
To calculate the total number of shoeboxes in the top row, we add up the shoeboxes in each row:
Top row: 4 shoeboxes
Top three rows: 4 + 9 = 13 shoeboxes
All rows: 4 + 9 + 16 = 29 shoeboxes
Option 3:
In the first row, we have 3 by 5 shoeboxes, which means 15 shoeboxes.
In the second row, we have 3 by 6 shoeboxes, which means 18 shoeboxes.
In the third row, we have 3 by 7 shoeboxes, which means 21 shoeboxes.
To calculate the total number of shoeboxes in the top row, we add up the shoeboxes in each row:
Top row: 15 shoeboxes
Top three rows: 15 + 18 = 33 shoeboxes
All rows: 15 + 18 + 21 = 54 shoeboxes
So, after each row has been completed for each pyramid option:
Option 1:
Top row: 6 shoeboxes
Top three rows: 18 shoeboxes
All rows: 38 shoeboxes
Option 2:
Top row: 4 shoeboxes
Top three rows: 13 shoeboxes
All rows: 29 shoeboxes
Option 3:
Top row: 15 shoeboxes
Top three rows: 33 shoeboxes
All rows: 54 shoeboxes
I hope this clears up your confusion! If you have any more questions, feel free to ask.
