Write out the volume of a prism
Formula
[tex]\begin{gathered} \text{Volume of a prism = square based area x height} \\ V=\text{ Bh} \\ \text{where B = Square based represents side length} \\ Height\text{ = h remain the same } \\ \end{gathered}[/tex]
Using the first side based length and volume to derive the equation
[tex]\begin{gathered} V=Bh=l^2h \\ V_1=16,s_1=2\text{ } \\ 2^2h\text{ = 16} \\ 4h\text{ = 16} \\ h\text{ = }\frac{16}{4} \\ h\text{ = 4} \end{gathered}[/tex]
Using the third side based length and volume to derive the equation
[tex]\begin{gathered} V=Bh=l^2h \\ V_3=64,s_3\text{ = 4} \\ 4^2h\text{ = 64} \\ 16h\text{ = 64} \\ h\text{ = }\frac{64}{16} \\ h\text{ = 4} \end{gathered}[/tex]
Therefore from the two result above, the equation can be deduced as
[tex]\begin{gathered} V=4s^2 \\ \sin ce\text{ height of the prism remain the same for all the table above } \end{gathered}[/tex]
Hence the equation that best represents the relationship is V = 4s²
