Surface Area Calculator

Calculate the surface area of various 3D geometric shapes

Radius (r):

Formula:

Surface Area = 4 × π × Radius²

A = 4πr²

Base Radius (r):

Height (h):

Formula:

Surface Area = π × r × (r + √(h² + r²))

A = πr(r + √(h² + r²))

Side Length (a):

Formula:

Surface Area = 6 × Side²

A = 6a²

Radius (r):

Height (h):

Formula:

Surface Area = 2 × π × r × (r + h)

A = 2πr(r + h)

Length (l):

Width (w):

Height (h):

Formula:

Surface Area = 2 × (lw + lh + wh)

A = 2(lw + lh + wh)

Radius (r):

Height (h):

Formula:

Surface Area = 2 × π × r × (2r + h)

A = 2πr(2r + h)

Sphere Radius (R):

Cap Height (h):

Formula:

Surface Area = 2 × π × R × h

A = 2πRh

Top Radius (r):

Bottom Radius (R):

Height (h):

Formula:

Surface Area = π × (r + R) × √((R - r)² + h²) + π × (r² + R²)

A = π(r + R)√((R - r)² + h²) + π(r² + R²)

Axis a:

Axis b:

Axis c:

Formula (Approximation):

Surface Area ≈ 4π × [((aᵇ × bᵇ + aᵇ × cᵇ + bᵇ × cᵇ)/3]^(1/b) where b ≈ 1.6075

Base Length (a):

Height (h):

Formula:

Surface Area = a² + 2a√((a/2)² + h²)

A = a² + 2a√((a/2)² + h²)

Surface Area: 0

Shape: Sphere
