The first face is a triangle with height 5in and base 12in

Traingular face area = 1/2 x bh

=1/2 x 12 x 5

= 30 in^2

The area of the other triangular base = 30 in^2

Area of left side face = Length x breadth

= 5 x 4 = 20in^2

Area of the slant face = Length x breadth

= 13 x 4 = 52in^2

Area of the bottom face = Length x breadth

= 12 x 4 = 48in^2

Total surface area = 30 in^2 + 30 in^2 + 20in^2 + 52in^2 + 48in^2

=180in^2
