Question

how do you find the surface area of a 3-d figure

Answer 1

Find the area of each surface then add them up

Answer 2

Use surface integrals

Answer 3

it shows it in a format that you would find volume with though.

Answer 4

If you know radial distribution of the surface integration in spherical coordinates would work wonders

Answer 5

im only a 7th grader i dont really understand any of that

Answer 6

I assume then you are trying to find the surface area of a cylinder, cube, cone, sphere, or some other geometric object.
We have formulas that we can use to find the surface area....which do you want to know?

Answer 7

rectangle prisms/ cubes/ triangular prisms

Answer 8

you will need to add the lateral area which is the area of the faces and the area of the base for the prisms... the area of the cubes will be the area of one face times 6.

Answer 9

do you have a specific question with edge lengths?

Answer 10

b=8x5 the three numbers are 8 5 and 6

Answer 11

can you give me a numerical equation for that?

Answer 12

ok, just a sec

Answer 13

thank you

Answer 14

2x(LxW)+2x(LxH)+2x(WxH)
2x(8x5)+2x(8x6)+2x(5x6)

Answer 15

2x40+2x48+2x30=
80+96+60=
236

Answer 16

so if a cube had edges of nine in it would be 9x9x2 twice?

Answer 17

in.*

Answer 18

or 9x9x6?

Answer 19

9x9x6

Answer 20

ok.

Answer 21

you have top and bottom
left and right
front and back

Answer 22

sure, no problem.
