The base of a prism is in the form of an equilateral triangle of perimeter 12 cm. The height of the prism is 8 cm. What is the volume of of the prism?
32√3cm3
Perimeter of the equilateral triangle is 12 cm
Hence each side of the equilateral triangle is 123=4cm
Area of the triangular base = √34×(4)2=√34×4×4
=4√3cm
Volume of prism = Base Area×Height
=4√3×8
=32√3cm3
