Answer:
348 km³
Step-by-step explanation:
The volume of the triangular prism can be calculated using the formula, Volume = base area of the prism*the length of the prism
Base area of the prism = area of triangle = ½*base of the triangle*height of the triangle
Base of the triangle = 12 km
Height of the traingle = 5.8
Therefore,
Base area = ½*12*5.8
= 6*5.8
Base area = 34.8 km²
Length of prism = 10 km
Volume of prism = base area*prism length
= 34.8*10
Volume of triangular prism = 348 km³
