To find the slant height of a square pyramid, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle formed by the height of the pyramid and half the length of the base.
The base of the pyramid is a square, which means that its length and width are equal. Therefore, half the length of the base is 18 inches / 2 = 9 inches.
Now we can use the Pythagorean theorem to find the slant height:
slant height^2 = height^2 + (0.5 * base length)^2
slant height^2 = 12^2 + 9^2
slant height^2 = 144 + 81
slant height^2 = 225
slant height = √225
slant height = 15 inches
So, the slant height of the square pyramid is 15 inches.
find the slant height of the square pyramid round to the nearest whole inch of necessary 12 IN 18 IN
