Answer:
Step-by-step explanation:
Alright, lets get started.
The total surface area of rectangular pyramid will be the area of all four faces and area of base.
The faces are triangular, so area will be = 
Area of face = 
Another face area = 
Each face has its similar another face. So total area of faces will be = 
Area of base = 
So total surface area =
square feet
Hence the total surface area is 596 square feet. : Answer
Hope it will help :)
Volume = 1/3 * area of the base * height
75 = 1/3 * 5^2 * h
h = 75 * 3 / 25 = 3*3 = 9 feet answer
