a metalworker is creating decorative points in the form of a triangular pyramid to go on top of a fence she is building she wants to know the surface area of each pyramid ise surface area formula to find the surface area of each pyramid based on figure responses 9.5cm 13.1cm 18.2cm 5.1cm
To find the surface area of a triangular pyramid, you can use the formula:
Surface Area = Base Area + (0.5 × Perimeter × Slant Height)
Given the following measurements:
Base Area = 9.5 cm
Perimeter = 13.1 cm
Slant Height = 18.2 cm
Substituting these values into the formula, we get:
Surface Area = 9.5 + (0.5 × 13.1 × 18.2)
Surface Area = 9.5 + (0.5 × 239.62)
Surface Area = 9.5 + 119.81
Surface Area = 129.31 cm²
Therefore, the surface area of each triangular pyramid is 129.31 cm².
