The surface area of the pyramid is given by the formula:
Surface Area = (1/2) * base * slant height
Substituting the given values, we have:
100 ft^2 = (1/2) * 6 ft * slant height
Multiplying both sides by 2 and dividing by 6:
200 ft^2 = slant height
To find the height of the base, we can use the Pythagorean theorem. The height, base, and slant height form a right triangle. Let's designate the height as h.
Using the Pythagorean theorem:
h^2 + (base/2)^2 = slant height^2
Substituting the given values:
h^2 + (6/2)^2 = 200^2
h^2 + 9 = 40000
h^2 = 39991
Taking the square root of both sides:
h = sqrt(39991) ≈ 199.98 ft
Rounded to the nearest tenth, the height is approximately 200 ft. Hence, neither of the provided options is correct.
