Answer:
186.94 cubic ft
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s= [tex]\frac{a + b + c}{2}[/tex]
A=ah+bh+ch+[tex]\frac{1}{2}[/tex] [tex]\sqrt{-a4+2(ab)2+2(ac)2-b4+2(bc)2-c4}[/tex]
6.2·5.5+8.5·5.5+9.8·5.5+[tex]\frac{1}{2}[/tex] ≈[tex]\sqrt{-6.24+2(6.2x8.5)2+2(6.2x9.8)2-8.54+2x(8.5x9.8)2-9.8x^{4}[/tex]
≈ 186.94 ft cubed
