What is the volume of a triangular prism whose base triangle has a base of 6cm and a height of 4cm, and the prism has a length of 10cm?
120 cm³
60 cm³
240 cm³
48 cm³
Maelezo
Area of base triangle = 1/2 * base * height = 0.5 * 6 cm * 4 cm = 12 cm². Volume of prism = Area of base * length = 12 cm² * 10 cm = 120 cm³
