Answer:
Outer surface area of this house = 187.85 yards²
Explanation:
Given:
Side = 6.5 yards
Height = 5.6 yards
Find:
Outer surface area of this house
Computation:
Outer surface area of this house = 2[lb + bh + hl] - lb
Outer surface area of this house = 2[(6.5)(6.5) + (6.5)(5.6) + (5.6)(6.5)] - (6.5)(6.5)
Outer surface area of this house = 2[42.25 + 36.4 + 36.4] - 42.25
Outer surface area of this house = 2[115.05] - 42.25
Outer surface area of this house = 187.85 yards²
