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 cm ? (1 point)
To find the missing width of the rectangular prism, we can use the formula for the surface area of a rectangular prism:
Surface Area = 2lw + 2lh + 2wh
Given:
Length = 6 cm
Height = 4 cm
Surface Area = 188 cm^2
Substitute the given 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
Therefore, the missing width of the rectangular prism is 7 cm.
