Answer: There are 21 layers of blocks.
Step-by-step explanation:
Since we have given that
Number of blocks in a box = 1344
Number of blocks in each layer = 64
We need to find the number of layer of blocks.
So, the number of layer of blocks is given by
[tex]\dfrac{1344}{64}\\\\=21[/tex]
Hence, there are 21 layers of blocks.
