Volume of a regular square pyramid (using the base and lateral edges)
Calculate the height, volume, and surface area of a regular square pyramid using the length of its lateral edges and the dimensions of its bases.

| Height h | |
| Volume V | |
| Surface Area S |
| \(\normalsize Square\ pyramid\\ (1)\ height:\hspace{60px} h={\large\frac{\sqrt{4l^2-2a^2}}{2}}\\ (2)\ volume:\hspace{50px} V={\large\frac{1}{3}}a^2h\\ (3)\ surface\ area:\hspace{10px} S=a^2+a\sqrt{a^2+4h^2}\\\) |
