Answer :

Answer:

V ≈ 7.4 m³

Step-by-step explanation:

The volume (V) of a triangular prism is calculated as

V = Al ( A is the area of the triangular face, l is the length of the prism )

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 2.6 and h = 1.9

A = [tex]\frac{1}{2}[/tex] × 2.6 × 1.9 = 1.3 × 1.9 = 2.47 m²

The length l of the prism is 3 m , then

V = 2.47 × 3 ≈ 7.4 m³ ( to 1 decimal place )
