Answer:
If the prism is trapezoid then you need to find the height and use this formula
1/2 x a+b x h
This has been done below you only need to fill in the height and do the shape for 3cm x 2cm as you haven't been clear in your question.
Volume = 8 x h x 10 = 80 x h cm^3
Hope this helps.
Step-by-step explanation:
Slope triangle prism and or rectangle
The area can be seen either by finding height of the triangle or working out the rectangle and halving the rectangle.
Step-by-step explanation:
Volume
6 x 8 = 48cm^2
48 x 5 = 230cm^2 for double (rectangle prism of 6 x8)
385/2 = 115cm^2 triangle slope prism
---------------
Area first
trapezoid front measures 6,5, 10
1/2 x 6 + 5 x h
=1/2 x 6 + 5 x h
= 8 x h x 10= 80 x h
Volume = 8 x h x 10 = 80 x h cm^3
