Answer:
The time required is 4.5 hours.

A furniture manufacturing company typically takes 18 hours to assemble 12 pieces of furniture. To determine the number of pieces of furniture that will be assembled in 3 hours, the following calculations were proposed; the one that allows to verify this relationship correctly is
The 12 pieces of furniture assembled in 18 hours
So, 1 piece assembled in 18 / 12 hours = 1.5 hours
And 3 pieces assembled in 3 x 1.5 = 4.5 hours
