Answer:

184

Step-by-step explanation:

A = 2(wl+hl+hw) = 2 · (6 · 2 + 10 · 2 + 10 · 6) = 184

Answer:

SA = 184 m²

Step-by-step explanation:

The opposite faces of the cuboid are congruent , then surface area (SA) is

SA = 2(2 × 6) + 2(6 × 10) + 2(2 × 10)

     = 2(12) + 2(60) + 2(20)

     = 24 + 120 + 40

     = 184 m²
