Answer:

  (c)  144 m²

Step-by-step explanation:

The surface area can be calculated from ...

  SA = 2(LW +H(L+W))

  SA = 2((6 m)(6 m) +(3 m)(6 m +6 m))

  = 2(36 m² +(3 m)(12 m)) = 2(36 m² +36 m²) = 2(72 m²)

  SA = 144 m²

_____

<em>Additional comment</em>

The units of area are square meters (m²). The units of volume are cubic meters (m³).
