After Reggie had stacked up 11 chairs in the basketball court after a conference, he noticed 3 things. Firstly, each of the chairs was stacked the same height above the other. Secondly, the foot of the sixth chair was 46 cm above that of the first. Thirdly, the chairs reached a height of 188.8 cm. What is the height of each chair?
Number of chairs that contributed to the height of 46 cm above the first chair
= 6 - 1
= 5

Height increase with each additional stacked chair
= 46 ÷ 5
= 9.2 cm

Number of chairs stacked on top of the first chair
= 11 - 1
= 10

Height increase of 10 additional stacked chairs
= 10 x 9.2
= 92 cm

Height of one chair
= 188.8 - 92
= 96.8 cm

Answer(s): 96.8 cm
