Answer:

The surface area of the rectangular pyramid is
$SA=109.50\ m^(2)$

Explanation:

we know that

The surface area of the rectangular prism is equal to the area of the rectangular base plus the area of the four triangular faces

so

SA=(8)(5)+2[14.75]+2[(1)/(2)(8)(5)]

SA=40+29.50+40

$SA=109.50\ m^(2)$
