Surface area formulas in geometry refer to the lateral surface and total surface areas of different geometrical objects. To recall, the surface area of an object is the total area of the outside surfaces of the three-dimensional object i.e, the total sum of the area of the faces of the object. It is measured in terms of square units. In other words, the surface area is the sum of all the areas of all the shapes that cover the surface of the object. On the other hand, the lateral surface area refers to the area of the sides of a shape, excluding its base and top area.

Surface Area Formulas:
| Shape | Lateral Surface Area (LSA) | Total Surface Area (TSA) |
|---|---|---|
| Cuboid | 2h(l + b) | 2(lb + bh + lh) |
| Cube | 4a2 | 6a2 |
| Right Prism | Base perimeter × Height | LSA + 2 (area of one end) |
| Right Circular Cylinder | 2πrh | 2πr(r + h) |
| Right Pyramid | (1/2) Perimeter of base × Slant Height | LSA + Area of Base |
| Right Circular Cone | πrl | πr(l + r) |
| Solid Sphere | 4πr2 | 4πr2 |
| Hemisphere | ½ × 4 × πr2 | 3πr2 |
