The formula for determining the total surface area of a rectangular prism is exprssed as
Total surface area = 2lw + 2lh + 2wh
Where
l = length = 11 inches
w = width = 5 inches
h = height = 4 inches
Therefore,
Total surface area = 2(11 * 5) + 2(11 * 4) + 2(5 * 4)
Total surface area = 110 + 88 + 40
Total surface area = 238 in^2
The correct option is C
