Lateral surface area (LSA) is the area of all the sides apart from the top and bottom faces.
The lateral surface area of the cuboid = Area of face AEHD + Area of face BFGC + Area of face ABFE + Area of face DHGC

| Shape | Parameters | Surface Area (Square units) | Volume (Cubic units) |
| Cuboid | Length = l Breadth = b Height = h | TSA = 2(lb + bh + lh) LSA = 2h(l + b) | V = l × b × h |
| Cube | Length = Breadth = Height = l | TSA = 6l 2 LSA = 4l 2 | V = l 3 |
| Cylinder | Radius = r Height = h | CSA = 2π × r × h TSA = 2πr(h + r) | V = πr 2 h |
| Cone | Radius = r Height = h Slant Height = l | CSA = πrl TSA = πr(l + r) | V = (1/3)πr 2 h |
| Sphere | Radius = r | CSA = TSA = 4πr 2 | V = (4/3)πr 3 |
| Hemisphere | Radius = r | CSA = 2πr 2 TSA = 3πr 2 | V = (2/3)πr 3 |
| Frustum | Radius of top circular part = r 1 Radius of bottom circular part = r 2 Height = h Slant height = l | CSA = π(r 1 +r 2 )l TSA = π(r 1 + r 2 )l + π(r 12 + r 22 ) | V = (1/3)πh(r 12 + r 22 + r 1 r 2 ) |
