Answer:
The correct answer is Option C.
Step-by-step explanation:
We are provided with the dimensions of the podium, including its length, width, and height, and need to determine its surface area.
To find the surface area of a cuboid, the formula used is 2(LW + WH + HL)
Referring to the provided figure, the dimensions of the upper cuboid are
L=2.5 ft., W=1.5 ft, H=1.5 ft


Since the upper face appears twice, it must be deducted to accurately calculate the area
The dimensions for the lower podium are
L=7.5 ft., W=1.5 ft, H=1.5 ft

Therefore, the overall surface area of the podium, including the bottom, is
19.5 + 49.5 - 3.75 = 65.25 square feet.
Thus, option C is indeed correct.
