A metalworker is creating decorative points in the form of triangular pyramids to go on top of a fence she is building. She wants to know the surface area of each pyramid. Use the surface area formula to find the surface area of each pyramid based on the figure

The surface area of the triangular pyramid can be calculated using the formula:
Surface Area = (1/2) * base perimeter * slant height
Since we know the surface area is 100 ft^2 and the base perimeter is 6 ft, we can rearrange the formula to solve for the slant height:
100 = (1/2) * 6 * slant height
200 = 6 * slant height
slant height = 200/6 = 33.33 ft (rounded to the nearest hundredth)
To find the height, we can use the Pythagorean theorem:
height^2 = slant height^2 - base length^2
height^2 = (33.33 ft)^2 - (6 ft)^2
height^2 = 1110.8889 - 36
height^2 = 1074.8889
height = √1074.8889 = 32.8 ft (rounded to the nearest tenth)
Therefore, the height of the base is approximately 32.8 ft.

Apologies for the misinformation. To find the correct height, we can use the Pythagorean theorem:
height^2 = slant height^2 - (1/2 * base length)^2
height^2 = (8 ft)^2 - (1/2 * 6 ft)^2
height^2 = 64 - 9
height^2 = 55
height ≈ √55
height ≈ 7.4 ft (rounded to the nearest tenth)
Therefore, the height of the base is approximately 7.4 ft.

height ≈ 7.4 ft (rounded to the nearest tenth)
Therefore, the height of the base is approximately 7.4 ft.

Apologies for the mistake. Let's calculate the correct height.
Using the Pythagorean theorem:
height^2 = slant height^2 - (1/2 * base length)^2
height^2 = (8 ft)^2 - (1/2 * 6 ft)^2
height^2 = 64 ft^2 - 9 ft^2
height^2 = 55 ft^2
height = √55
height ≈ 7.42 ft (rounded to the nearest hundredth)
Therefore, the height of the base is approximately 7.42 ft.
Using the Pythagorean theorem:
height^2 = slant height^2 - (1/2 * base length)^2
height^2 = (8 ft)^2 - (1/2 * 6 ft)^2
height^2 = 64 ft^2 - 9 ft^2
height^2 = 55 ft^2
height = √55
height ≈ 7.42 ft (rounded to the nearest hundredth)
Therefore, the height of the base is approximately 7.42 ft.
