Answer:
192
Explanation:
Volume of triangular prism = area of base * length
The base of the triangular prism is a triangle
The area of a triangle can be calculated by multiplying the base length by the height and dividing that by 2
The base has a base length of 4m and a height of 8m
So area of base =
4 * 8 = 32
32 / 2 = 16
So the area of the base is 16m²
The prism has a length of 12m and we have identified that the area of the base is 16 so volume = 12 * 16
12 * 16 = 192
So the volume of the triangular prism is 192m³
