To find the surface area of the two-tiered steps, we first need to calculate the surface area of each individual step and then add them together.
Surface area of the first step:
Length = 14 inches
Width = 13 inches
Surface area = Length x Width = 14 inches x 13 inches = 182 square inches
Surface area of the second step:
Length = 17 inches
Width = 6.5 inches
Surface area = Length x Width = 17 inches x 6.5 inches = 110.5 square inches
Surface area of the third step:
Length = 8.5 inches
Width = 6.5 inches
Surface area = Length x Width = 8.5 inches x 6.5 inches = 55.25 square inches
Total surface area of the two-tiered steps:
182 square inches + 110.5 square inches + 55.25 square inches = 347.75 square inches
Therefore, the total surface area of the two-tiered steps is 347.75 square inches.
