Answer 1

109.5

Explanation:

Answer 2

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)`
