Surface area of pyramid # = 40#

Explanation:

The square pyramid has 5 parts, 4 triangles and one square.

Area of square# = a^2 = 4^2 = 16#
Area of one triangle # = (1/2)*b*h = (4*3)/2 = 6#

Area of 4 triangles + one square will be the total surface area of the square based pyramid.

#:.# Total surface area # = 16 + (4*6) = 16 + 24 = 40#
