Option A is the answer.
Step-by-step explanation:
Total number of nails in small a box = 150
Its given that the jumbo box is made by tripling the smaller box.
By tripling the 3 dimensions we will have 3 x 3 x 3 times the original capacity.
The number of nails will be 27 times the original volume.
Hence, the new count is :
[tex]150\times27=4050[/tex] nails.
