Answer: There are 400 white tiles which Ron will need.
Step-by-step explanation:
Since we have given that
Number of rows to cover the counter = 8
Number of tiles to cover each 8 rows = 54 square tiles
So, total number of tiles to cover 8 rows is given by
\(8\times 54=432\)
Number of groups on which 4 blue tiles are placed = 8
Total number of blue tiles on 8 groups is given by
\(8\times 4=32\)
Remaining are the white tiles so, it is given by
\(432-32=400\)
So, there are 400 white tiles which Ron will need.
