Answer:
a) 252 square feet
Surface area of triangular prism = 252 square feet
Step-by-step explanation:
Explanation:-
Given diagram Base = 3 feet
Height of the triangular = 4 feet
The slant height of triangular prism 'l' =20 feet
The hypotenuse of the triangle 'c' = 5 feet
prism base area 'p' = h+b+c = = 4 +3+5 =12
Surface area of triangular prism
=
= b h + p l
= 3 ×4 + 12×20
= 252 square feet
Final answer:-
Surface area of triangular prism = 252 square feet
