The Volume of a figure measures what the figure holds when filled even with air. A bh Ls1 s2 s3 Where A is the surface area b is the bottom edge of the base triangle h is the height of the base triangle L is the length of the prism and s1 s2 and s3 are the three edges of the base triangle. To know the area of a quarter of a circle this formula will be applied.
The formula for finding the surface area of a triangular prism is given as.
All of the area formulas for general convex quadrilaterals apply to parallelograms. Learn more at Area of Plane Shapes. In the case of arc length and sector area you will only be dealing with a portion. We can also put the shape on a grid and count the number of squares.
