Lateral Area, namely the area of its sides, namely excluding its base.
well, the pyramid is standing on one of its triangular faces, so we'll have to exclude that.
now, let's notice, is a square pyramid, so it has an 8x8 square, and it has triangular faces that have a base of 8 and a height of 22.
![\bf \stackrel{\textit{square's area}}{(8\cdot 8)}~~+~~\stackrel{\textit{3 triangular faces' area}}{3\left[ \cfrac{1}{2}(8)(22) \right]}\implies 64+264\implies 328](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gabz1ppp1r2sx74uk8fvz7g0t4ucchygar.png)
