Answer 1

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
