Find Surface Area of the triangular prism using the net provided.

Answer 1

984 cm²

Explanation:

Surface area of triangular prism:

`\boxed{\text{\bf Surface area of triangular prism = bh + (s_1 + s_2 + s_3)*l}}}`
`\boxed{\text{\bf Surface area of triangular prism = bh + $ \bf (s_1+s_2 + s_3)*l $ }}`

nb is the base of the triangle. b= 10 cm

h is the altitude of the triangle. h = 12 cm

s₁, s₂, s₃ are the sides of the triangle. s₁ = 13 cm, s₂ = 13 cm, s₃ = 10 cm

l is the length of the prism. l = 24 cm

Surface area = 10*12 + (13 + 13 + 10) * 24

= 120 + 36* 24

= 120 + 864

= 984 cm²
