Rules for finding volume of prisms<br />
Rectangular prism (cuboid)<br />
Volume = length x width(breadth) x height<br />
= l x w x h<br />
V = lwh (or lbh)<br />
Cube<br />
Volume = length x width(breadth) x height<br />
= l x l x l<br />
V = l 3<br />

Triangular prism<br />
Volume = Area of end region x length<br />
= 1 / 2<br />
x base x height x length<br />
= 1 / 2<br />
x b x h x l<br />
V = 1 / 2<br />

Trapezoidal prism<br />
Volume = Area of end region x length<br />
= 1 / 2<br />
