The correct answer is 96 ft³. In order to find the volume of a prism, you first have to find the area of the faces and then multiply by the distance between them. In this case, we're finding the area of a triangle using the base, 6, and the height, 4, and then multiplying by 8.
A = 1/2bh Area of a triangle
A = 1/2(4 x 6) Substitute
A = 24 / 2 Multiply
A = 12
So, the area of the triangle is 12 ft². Now, we just multiply that by 8 to get the answer.
12 x 8 = 96
So, the volume of the triangular prism is 96 ft³.
Hope this helps!
