Look at the triangular prism. Work out the volume of the prism.

xz_007 [3.2K]

Answer:

See explanation

Step-by-step explanation:

The question has missing details, as the diagram of the prism is not shown.

However, I'll solve using a general rule.

The volume of a triangular prism is:

$Volume = \frac{1}{2}* b * h * l$

Where

$b = base$

$h = height$

$l = length$

Take for instance:

$b = 20cm$

$h = 10cm$

$l = 5cm$

The volume is:

$Volume = \frac{1}{2} * 20cm * 10cm * 5cm$

$Volume = 10cm * 10cm * 5cm$

$Volume = 500cm^3$

Another instance (see attachment).

From the attachment:

$b = 4.5cm$

$h = 5cm$

$l = 8cm$

The volume is:

$Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm$

$Volume = 2.25cm * 5cm * 8cm$

$Volume = 90cm^3$
