Answer 1

Explanation:

Perimeter of the triangular base = 10 + 10 + 16

= 36 ft

Height of the prism = 15 ft

Base area = Area of the triangle

=
`(1)/(2)(\text{Base})(\text{Height}})`

=
`(1)/(2)(16)(6)`

= 48 square ft

Surface area of the triangular prism = 2(base area) + (perimeter × height)

= 2(48) + 36(15)

= 96 + 540

= 636 square ft
