Answer:
384
The step-by-step explanation for HEIGHT first:
[tex]h=\sqrt{s^{2} } -(\frac{a}{2}) ^{2}[/tex]
[tex]h=\sqrt{10^{2} } -(\frac{12}{2} )^{2}[/tex]
[tex]h=\sqrt{10^{2} } -6^{2} = \sqrt{64} =[/tex] 8 cm is the height
step-by-step explanation:
v = [tex]\frac{1}{3}[/tex] · b · h
v = [tex]\frac{1}{3}[/tex] ( 12 · 12 ) ( 8 )
v = [tex]\frac{1}{3}[/tex] ( 144 ) ( 8 )
v = 384 cm³
