Surface Area and Volume formulas for class 10th.


Surface Area of a cuboid of length (l), breadth (b), and height (h) = 2 (lb + bh + lh)

Lateral Surface Area of cuboid = 2 (l + b)h

Surface Area of a cube = 6 ✕ l2 where l is the length

Lateral Surface Area of cube = 4 ✕ l2, where l is the length

Volume of cube = l3

Lateral Surface Area of a Cylinder = 2πrh

Total Surface Area of a Cylinder = 2πr (h+r)

Volume of Cylinder = πr2 h

Lateral Surface Area of Cone = πrL

Total surface area of cone = πr ( L+ r)

Volume of Cone = ⅓ (πr2 h)

Surface Area of Sphere= 4 πr2

Volume of Sphere = 4/3 (πr3)

Volume of a frustum of a cone = 1/3 πh(r₁2 + r₂2 + r₁r₂)
