The pyramid is 8.8 m 9 m 6 m 2 m When finding the surface area of the rectangular pyramid, what dimension will be used to find the height of the triangular sides?
__ m
To find the height of the triangular sides of the rectangular pyramid, we need to use the slant height. The slant height is the height of each triangular face of the pyramid, which can be calculated using the Pythagorean theorem.
In this case, we can use the dimensions of the pyramid to find the slant height. The slant height can be calculated using the dimensions of the base (8.8 m and 9 m) and the height of the pyramid (6 m).
Using the Pythagorean theorem:
slant height = √(base/2)^2 + height^2
slant height = √(8.8/2)^2 + 6^2
slant height = √(4.4)^2 + 36
slant height = √(19.36 + 36)
slant height = √55.36
slant height ≈ 7.44 m
Therefore, the dimension used to find the height of the triangular sides of the pyramid is 7.44 m.
