Let the missing width be "w".
The surface area of a rectangular prism can be calculated using the formula:
Surface area = 2lw + 2wh + 2lh
Substituting the given values, we get:
188 = 2(6)(w) + 2(4)(w) + 2(6)(4)
Simplifying:
188 = 12w + 8w + 48
188 = 20w + 48
20w = 140
w = 7
Therefore, the missing width of the rectangular prism is 7 cm.
