so slant height is the length of a lateral face
imagine a pyramid was hollow.
the height is the distance from center of the bottom... to the point.
the slant height tho... imagine if u unfolded it and laid it out flat on the ground
the slant height is the distance from the point of a face to the middle of the bottom. so your splitting the face into 2 equal triangles... right down the middle. slant height is bigger... always
