Question

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? A. 13.75 centimeters B. 76.25 centimeters C. 33.2 centimeters D. 3.75 centimeters

Answer 1

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 = $90 - 23.5$ = 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 = $66.5 -33.3$ = 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 = $33.2-19.45$ = 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.
