Question

what is the surface area formula?

Answer 1

Of what object?

Answer 2

all objects haha

Answer 3

Surface Area of a Cube = 6 a 2

Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac

Surface Area of Any Prism

Surface Area of a Sphere = 4 pi r 2

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h

does that help?

Answer 4

Surface Area of Any Prism = Lateral area + Area of two ends

Answer 5

there is no fixed formula for 3D shapes. for total surface area you just have to add the surface areas of all the sides. for example, if you have a cube with length 6cm, your total surface area would be (6*6) * 6 which would be 216 cm^2
