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?

Answer 1

Total length of the wood = 90 centimeter.
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
