Round to the nearest tenth :)

Good morning

Surface area (rounded to the nearest tenth) = 193.3 in²

Step-by-step explanation:

Surface area of this prism = 2×(base’s area) + lateral area

base’s area = (1.9 × 7)/2 = (1,9×7)÷2 = 6.65

lateral area = 12×(7+3+5) = 180

then

Surface area of this prism = 2×(base’s area) + lateral area

                                           = 2×(6.65)+180

                                           = 193.3
