Answer:

Step-by-step explanation:

Surface area of the 4 sided pyramid  = base area + 4 time each triangle area

                     = (s²)  + 4 × 1/2(b)(h)

                     = (10)(10)  + 4 × (1/2)(10)(8)

                     = 100 +  4(1/2)(10)(8)

                     = 100 + 160

                     = 260
