Answer
H = 5
Explanation
The surface area of the special rectangle box is given as
S = 4LW + 2WH
where
S = 184
L = 9
W = 4
We are then told to find H
To do that, we will just substitute for the variables whose numbers are given and solve for H
S = 4LW + 2WH
184 = 4×9×4 + 2×4×H
184 = 144 + 8H
We can rewrite this as
144 + 8H = 184
8H = 184 - 144
8H = 40
Divide both sides by 8
(8H/8) = (40/8)
H = 5
Hope this Helps!!!
