The surface area of any given object is the area or region occupied by the surface of the object. The surface area of 3 D shapes is similar to the area of 2 D shapes. Recall that the space occupied by a two-dimensional flat surface is called the area. It is measured in square units...

On a N * N grid, we place some 1 * 1 * 1 cubes. Each value v = grid[i][j] represents a tower of v cubes placed on top of grid cell (i, j). Return the total surface area of the resulting shapes. Example 1...
The surface area is always recorded in square units. Prisms are 3D shapes that have a polygonal base and rectangular faces. A rectangular prism has 666 rectangular faces, including 444 rectangular lateral faces and 222 rectangular bases. For example, Calculate the area of each face and then add...

由于之前做过那道三维物体投影的题 [Projection Area of 3D Shapes](https://www.cnblogs.com/grandyang/p/10865485.html),所以博主很思维定势的想到是不是也跟投影有关,然后又想当然的认为三维物体每一个面的面积就是该方向的投影,那么我们把三个方向的投影之和算出来,再乘以2不就是表面积了么?实际上这种方法...
The surfaces of some common solids are listed below: Surface Area of 3D Shapes The surface area of a solid is the sum of the areas of each face. When finding the surface area of 3D figures, consider it as unfolding the shape or flattening it out. Then find the area of each plane sur...
