The formula for the surface area of a rectangular prism is:
S.A. = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height.
Substituting the given values, we have:
188 = 2(6)(4) + 2(6)(w) + 2(4)(w)
188 = 48 + 12w + 8w
188 = 48 + 20w
140 = 20w
w = 7
Therefore, the missing width of the rectangular prism is 7 cm.
