## How to Find the Surface Area of an Object

Surface area is the measure of the area of the surface of a 3-dimensional geometric shape or object and is measured in square units, such as square inches or feet. You can find the area of each side of an object and add them all together to find the total surface area of the object. For common shapes, find the surface area using the formulas below.

One important consideration when measuring a shape to find the surface area is to take all measurements using the same unit of measure. If your measurements are in different units, convert each measurement to the unit you want the results in. Use our length unit conversion calculators to convert your measurements to a consistent unit.

### Cube

cube surface area = 6e^{2}

e = edge length

Calculate cube surface area

### Rectangular Prism

prism surface area = 2lw + 2lh + 2wh

l = length

w = width

h = height

Calculate rectangular prism surface area

### Sphere

sphere surface area = 4πr^{2}

r = radius

Calculate sphere surface area

### Cylinder

cylinder surface area = 2πr(r + h)

base surface area = 2πr^{2}

lateral surface area = 2πrh

r = radius

h = height

Calculate cylinder surface area

### Cone

cone surface area = πr(r + r^{2} + h^{2})

base surface area = πr^{2}

lateral surface area = πrr^{2} + h^{2}

r = radius

h = height

Calculate cone surface area

### Pyramid

pyramid surface area = e^{2} + 2e(e ÷ 2)^{2} + h^{2}

base surface area = e^{2}

lateral surface area = 2e(e ÷ 2)^{2} + h^{2}

e = edge length

h = height

Calculate pyramid surface area

### Capsule

capsule surface area = 2πr(2r + h)

end surface area = 4πr^{2}

lateral surface area = 2πrh

r = radius

h = height

Calculate capsule surface area

### Cap

cap surface area = π(r^{2} + h^{2}) + πr^{2}

base surface area = πr^{2}

top surface area = π(r^{2} + h^{2})

r = radius

h = height

Calculate cap surface area
