What is the surface area of a cube with dimensions of 12=L 16=W 22=H???
$${\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{LW}}{\mathtt{\,\small\textbf+\,}}{\mathtt{WH}}{\mathtt{\,\small\textbf+\,}}{\mathtt{LH}}\right)$$
$${\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{16}}{\mathtt{\,\small\textbf+\,}}{\mathtt{16}}{\mathtt{\,\times\,}}{\mathtt{22}}{\mathtt{\,\small\textbf+\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{22}}\right) = {\mathtt{1\,616}}$$
.$${\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{LW}}{\mathtt{\,\small\textbf+\,}}{\mathtt{WH}}{\mathtt{\,\small\textbf+\,}}{\mathtt{LH}}\right)$$
$${\mathtt{2}}{\mathtt{\,\times\,}}\left({\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{16}}{\mathtt{\,\small\textbf+\,}}{\mathtt{16}}{\mathtt{\,\times\,}}{\mathtt{22}}{\mathtt{\,\small\textbf+\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{22}}\right) = {\mathtt{1\,616}}$$
