Good morning
Answer:
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
