Calculate Volume and Surface Area
Measure the base width and height of the triangle (perpendicular height from base to opposite vertex).
Why: The triangular cross-section determines the cross-sectional area. This area, when extended as the prism length, gives volume.
Compute the triangle area: Area = 0.5 × base × height
Why: The base area is the fundamental component. Volume = base area × length.
Measure how far the triangular cross-section extends (perpendicular to the triangle face).
Why: Length extends the cross-sectional area into 3D space. Different lengths from the same triangle create different volumes.
Volume = base area × length; Surface area includes two triangle faces plus three rectangular faces.
Why: Surface area determines coating/material needed. It includes the ends and all three rectangular sides.
Check that all measurements form a valid three-dimensional shape.
Why: Invalid dimensions (negative or zero) indicate measurement errors. Verification ensures geometric validity.
