Answer:
40 m
Step-by-step explanation:
Use this equation for showing your work:
9x2=18 + 6x2=12 + 5x2=10
The front and back side of the triangle is labeled 5 m, because they’re the exact same shape. The same thing can be said for the other numbers. So just add them all twice.
About 70.71068 m is your answer.
V=1/4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
≈70.71068
