Answer:
2181.2mm^3
Step-by-step explanation
The picture shown is a triangular based prism and the formula for calculating its volume is expressed as;
Volume = 1/2 * area of cross section * length
Area of cross section = base * height
Given
Base = 13.3mm
Length = 16mm
Height = 20.5mm
Substitute into the volume formula;
Volume = 1/2 * 13.3* 20.5* 16
Volume = 4,362.4/2
Volume of the figure = 2181.2mm^3
