Answer:   264 cm²

Step-by-step explanation:

The surface area of a rectangular prism: SA=2(wl + hl + hw)

Since l = 15 cm; w = 2 cm & h = 6 cm

∴ by substituting into the formula SA = 2 [(2)(15)l + (6)(15) + (6)(2)]

                                                              = 2 [ 30 + 90 + 12 ]

                                                              = 264 cm²
