Question

Find the surface area of the prism.

Answer 1

a). B = 24 yd²

b). h = 8 yd

c). S.A. = 240 yd²

Explanation:

Area of the triangular base B =
`(1)/(2)(\text{Base of the right triangle})(\text{height of the base triangle})`

=
`(1)/(2)(8)(6)`

= 24 yd²

Height of the prism 'h' = distance between the triangular bases

= 8 yd

Perimeter of the triangular base = leg 1 + leg 2 + hypotenuse

= 8 + 6 + 10 = 24 yd

Surface area = 2B + Ph

= (2×24) + (24×8)

= 48 + 192

= 240 square yds
