(B) Given that the edge length of the cube is $a = 16\, cm$.The formula for the total surface area of a cube is $6a^2$.Substituting the value of $a$ into the formula:Total Surface Area $= 6 \times (16)^2\, cm^2$$= 6 \times 256\, cm^2$$= 1536\, cm^2$.Therefore,the total surface area of the cube is $1536\, cm^2$.
