To calculate the number of nails needed using Sarah's rule of dividing the length of the beam by 3, we can find the results for the given lengths:
- Length of Beam: 9 inches →
nails - Length of Beam: 15 inches →
nails - Length of Beam: 8 inches →
nails (round down to 2 nails) - Length of Beam: 10 inches →
nails (round down to 3 nails) - Length of Beam: 39 inches →
nails
Based on these calculations, you can fill in the response areas as follows:
- For Length of Beam 9: Number of Nails = 3
- For Length of Beam 15: Number of Nails = 5
- For Length of Beam 8: Number of Nails = 2
- For Length of Beam 10: Number of Nails = 3
- For Length of Beam 39: Number of Nails = 13
If any of the numbers are not pre-filled or do not match with your response area, please let me know!
