What is the missing width of a rectangular prism with a length of 6 cm, a height of 4 cm, and a surface area of 188 cm2

To find the missing width of the rectangular prism, we first need to calculate the surface area of the rectangular prism using the formula:

Surface Area = 2lw + 2lh + 2wh

Given that the length (l) is 6 cm, the height (h) is 4 cm, and the surface area is 188 cm2, we can substitute these values into the formula and solve for the missing width (w):

188 = 2(6)(w) + 2(6)(4) + 2(4)(w)
188 = 12w + 48 + 8w
188 = 20w + 48
20w = 140
w = 7 cm

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