For this qustion of a right-angle triangle block, as long as you know the area of the right-angle triangle and the height of the block, it is sufficient to calculate the total surface area. All the variations would be around either the area or the height.
From the area of the right-angle triangle you can get the values for the three sides of the right-angle triangle. Then with the height, you can get the total surface area. |
