Answer:
Here,
given that : - area of base(Bottom surface area) surface = 84.3ft.sq
So, the area of top surface area is same as bottom surface area, that is
= 84.3ft.sq
And, given that lateral dimensions.
Height (Breadth ) = 4ft
length = 7ft
So, lateral surface area is
= 4ft×7ft×5 = 140ft.sq
So, final answer is
total area = 84.3×2 + 140 = 308.6ft.sq
