Answer:
volume of a rectangular prism (v) = 64 cm³
Length (l) = 8 cm
width (w) = 4 cm
height (h) = ?
volume of a rectangular prism = Length × width × height
[tex]v = lwh \\ \\ h = \frac{v}{lw} \\ \\ h = \frac{64 \: {cm}^{3} }{8 \: cm \times 4 \: cm} = \frac{64 \: {cm}^{3} }{32 \: {cm}^{2} } \\ \\ \\ h = 2 \: cm[/tex]
I hope I helped you^_^
