Since, Jesse is building a spice rack.
The total length of wood = 90 centimeters
He cuts the board into three parts.
The length of the first part = 23.5 cm
So, remaining length of the board = = 66.5 cm
Now, he cuts the second part.
The length of the second part = 33.3 cm
So, now remaining part of the board = = 33.2 cm
Now, he cuts the third part of the board.
The length of the third part = 19.45 cm
