Answer:
1298ft^2
Explanation:
Total surface area of a square prism is expressed as;
TSA = 2B + Ph
B is the base area
P is the perimeter of the base
h is the height of the prism
Base area = Length * Length
Base Area = 11 * 11
Base Area = 121ft^2
Perimeter = 4L
Perimeter = 4(11) = 44ft
h = 24ft
Substitute into the formula;
TSA = 2(121) + 44(24)
TSA = 242 + 1056
TSA = 1298ft^2
Hence the total surface area of the prism is 1298ft^2
