Question

Kai is making a chessboard using pieces of wood that measure 1 square inch.

when he finishes, the chessboard will have an area of 64 square inches.
how many pieces of wood should he put along each side?


a.
64 pieces of wood

b.
642 pieces of wood

c.
8 pieces of wood

d.
82 pieces of wood

Answer 1

Answer: it will be 8

Step-by-step explanation: because 8×8=64

Answer 2

The correct option will be: c. 8 pieces of wood.

Explanation:

Suppose, the number of pieces of wood along each side of the chess board is
`x`

The area of each piece of wood is given as 1 square inch. So, the length of each piece of wood will be:
`√(1)= 1` inch.

And the total length of
`x` number of pieces of wood will be:
`1x` inches.

Given that, the area of the chess board is 64 square inches. So, the length of each side will be:
`√(64)=8` inches.

Thus, the equation will be.........

`1x=8\\ \\ x=(8)/(1)=8`

So, he should put 8 pieces of wood along each side.
