SOLUTION:
Case: Rectangular pyramid
Method:
The base has a dimension 5mm by 5mm
The height is 3mm
The Volume, therefore:
[tex]\begin{gathered} V=\frac{1}{3}\times l\times w\times h \\ V=\frac{1}{3}\times5\times5\times3 \\ V=\frac{75}{3} \\ V=25mm^3 \end{gathered}[/tex]
Final answer:
The volume, V= 25 cubic millimeters
