 Question from olwethu, a student: volume of wedge that have side 3,3 cm and 6,2 cm and 20 cm long?

HI,

I assume your wedge looks like this.

This shape is called a triangular prism and its volume is the area of the triangular base times the height. The height is 3,3 cm and the area od a triangle is half the base times the height. The base of the triangle is 6,2 cm and its height is 20 cm. Thus the volume of the wedge is

$\frac12 \times 6,2 \times 20 \times 3,3 \mbox{ cubic centimeters.}$
