The total surface area is 125 square yards.
The base area is 37.5 square yards.
Hence, the area of the curved surface is 125 - 37.5 = 87.5 square yards.
According, to the formula, the area of the curved surface is , where b is the base length and s = slant height.
Here, it is given that b = 5 yards.
Thus, .
