Answer:
V≈278.85
Step-by-step explanation:
AB=s(s﹣a)(s﹣b)(s﹣c)
V=ABh
s=a+b+c
2
Solving forV
V=1
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1
4·8·﹣64+2·(6·12)2+2·(6·12)2﹣124+2·(12·12)2﹣124≈278.8548
Because 1 meter is 1000 millimeters.
32 meters would be 32,000
But there is a decimal point in 3.2, so you would erase one 0.
So 3.2 meters=3,200 millimeters
