[AI-generated answer — Bot GPT 3.5]

The formula for the surface area of a rectangular prism is SA = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

Given:
Length (l) = 6 cm
Height (h) = 4 cm
Surface Area (SA) = 188 cm2

Plugging in the values into the formula:
188 = 2(6)(w) + 2(4)(6) + 2(4)(w)
188 = 12w + 48 + 8w
188 = 20w + 48
140 = 20w
w = 7 cm

Therefore, the missing width of the rectangular prism is 7 cm.
