Jesse is building a spice rack. he cuts three lengths of wood from a 90-centimeter board. the first length is 23.5 centimeters. the second length is 33.3 centimeters. and the third length is 19.45 centimeters. how much of the original board remains after jesse makes his cuts?
Length of the first cut wood = 23.5 centimeters
Length of the second cut wood = 33.3 centimeters
Length of the third cut wood = 19.45 centimeters.
Total length of the woods cut
from the original piece = 23.5 + 33.3 + 19.45 centimeters
= 76.25 centimeters
Amount of original board
that remains after Jesse makes his cuts = 90 - 76.25 centimeters
= 13.75 centimeters
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
Now, the remaining part of the board = = 13.75 cm
So, the length of the original board after cutting the three parts = 13.75 cm
So, Option A is the correct answer.
