area of triangular prism:
[tex]\dashrightarrow \sf (4+3+5) \ x \ 7 \ + 3 \ x \ 4[/tex]
[tex]\dashrightarrow \sf 96 \ ft^2[/tex]
Answer:
Step-by-step explanation:
A = 7 ft
B = 5 ft
C = 3 ft (base of the triangle)
D = 4 ft (height of the triangle)
Surface area of prism = base *height + ( B + C + D)*A
= 4*3 + (5 + 3 + 4) * 7
= 12 + 12 *7
= 12 + 84
= 96 square ft.
