To find the height of the base, we can use the formula for the surface area of a triangular pyramid:

Surface area = (base area) + (lateral area)

The formula for the base area of a regular triangular pyramid is:

Base area = (base length * base height) / 2

In this case, the base length is 6 ft. To find the base height, we can use the Pythagorean theorem:

(base height)^2 + (slant height)^2 = (base length)^2

(base height)^2 + 8^2 = 6^2
(base height)^2 + 64 = 36
(base height)^2 = 36 - 64
(base height)^2 = -28

Since we cannot have a negative base height, we know that there is an error in the given values. Therefore, it is not possible to determine the height of the tent using the given information. None of the provided options are correct.
