Answer:
The total surface area of the given shape is
= 253.5 
Step-by-step explanation:
Side of the square = 6.5 in
We know that area of the square is given by the equation
⇒ A = 
Put the value of a in above equation we get
⇒ A = 6.5 × 6.5
⇒ A = 42.25 
We know that the given shape has 6 surfaces so total surface area of the given shape is given by
⇒
= 6 × 42.25
⇒
= 253.5 
Therefore the total surface area of the given shape is
= 253.5
