Answer:

20 +4√2

Step-by-step explanation:

Find the total area the regular pyramid = A + 1/2ps

A is the Base area

p is the perimeter of the base

s is slant height

A = 1/2 * 4 * 4

A = 16/2

A = 8

p = 4 + 4 + (√4^2+4^2)

p = 8 + √32

p = 8 + 4√2

s = 4

Substitute

TSA = 8 + 8 + 4√2 + 4

TSA = 20 +4√2

Hence the total surface area is 20 +4√2
