Answer:
the answer should be 131
Step-by-step explanation:
the base of the triangular prism is 2.5x8=20
the 2 sides are equal and is 8x6=48 but there is 2 so it doubles so it is 96
and the 2 triangles are A=1/2 BH but since there is 2 triangles dont divide it should be 2.5x6 and the total should be 131 when added all together
