∻Solution by Steps∻ ‖ step 1 ⋮ Given the right triangle within the pyramid, we use the Pythagorean theorem $a^2 + b^2 = c^2$, where $a$ and $b$ are the legs and $c$ is the hypotenuse. ‖ ‖ step 2 ⋮ We know the length of one leg $a = 5$ units (half the base of the pyramid) and the hypotenuse $c = 8$ units (the slant height of the pyramid). ‖ ‖ step 3 ⋮ We need to find the length of the other leg $h$, which represents the vertical height of the pyramid. ‖ ‖ step 4 ⋮ Substitute the known values into the Pythagorean theorem: $5^2 + h^2 = 8^2$. ‖ ‖ step 5 ⋮ Solve for $h^2$: $h^2 = 8^2 - 5^2$. ‖ ‖ step 6 ⋮ Calculate $h^2$: $h^2 = 64 - 25$. ‖ ‖ step 7 ⋮ Simplify $h^2$: $h^2 = 39$. ‖ ‖ step 8 ⋮ Take the square root of both sides to find $h$: $h = \sqrt{39}$. ‖ ‖ step 9 ⋮ Calculate $h$: $h \approx 6.2$ units when rounded to the nearest tenth. ‖ ∻Answer∻ ⚹ The height is $6.2$ units. ⚹ ∻Key Concept∻ ⚹Pythagorean Theorem⚹ ∻Explanation∻ ⚹The vertical height of the pyramid is found by using the Pythagorean theorem on the right triangle formed by the height, half the base, and the slant height of the pyramid.⚹◊What is the formula to calculate the vertical height $h$ of a square pyramid using the base length and the slant height?⍭ Generate me a similar question◊
