Answer 1

Can you show the picture/draw a figure?

Answer 2

Okay so split the shape into its three components, the rectangle and the two triangular prisms. even though the shapes do not look like that at the moment due to differening heights at different ends, you may average the different hieights at either end to form the correct lengths for a regular shape

Answer 3

Note: This works in this case because of the uniform differences along the changes. No sudden increase/decrease in change
