Answer:
90 ft
Step-by-step explanation:
Surface area = 2(6 × 3 + 3 × 3 + 3 × 6)
= 2(18 + 9 + 18)
= 2 × 45 = 90 ft
Answer:
90 ft
Step-by-step explanation:
Times the length by the width of one side: 6 x 3= 18
Times 18 by 4 to get the surface area of the 4 rectangular sides: 18 x 4= 72
Times 3 by 3 to get the bottoms surface area: 9
Times 9 by 2 to get both the top and bottoms surface area: 18
Add 72+18 to get the total surface area: 90 ft
