Answer:
The correct option will be: c. 8 pieces of wood.
Step-by-step explanation:
Suppose, the number of pieces of wood along each side of the chess board is [tex]x[/tex]
The area of each piece of wood is given as 1 square inch. So, the length of each piece of wood will be: [tex]\sqrt{1}= 1[/tex] inch.
And the total length of [tex]x[/tex] number of pieces of wood will be: [tex]1x[/tex] inches.
Given that, the area of the chess board is 64 square inches. So, the length of each side will be: [tex]\sqrt{64}=8[/tex] inches.
Thus, the equation will be.........
[tex]1x=8\\ \\ x=\frac{8}{1}=8[/tex]
So, he should put 8 pieces of wood along each side.
Answer: it will be 8
Step-by-step explanation: because 8×8=64
