Question

surface area of a square pyrimid

Answer 1

Be more specific?

Answer 2

square pyrimid of 6 6 and 8

Answer 3

base 6, width 6, and height 8?

Answer 4

Are you looking for volume?

Answer 5

yep



im just lost

Answer 6

no surface area

Answer 7

one face is equal to base times height divided by 2.

to find the height of the face; you use the fact that 8 and 3 are the legs of another triangle with the hypotenuse of it being your surce height...does that make sense?

Answer 8

SA would be Length x Width

Answer 9

yessssssss but this is on a pyrimid

Answer 10

A square pyramid is just a square with 4 triangles on top of it. So take it step by step.

A square has area side^2.
A triangle has area (1/2)*base*height.
There's 4 triangles, all with the same area.

Add the (area of the square) + 4*(area of triangle)

Answer 11

sqrt(64 + 9) = sqrt(73)

the surface area of the entire pyramid, not counting the bottom is:

6sqrt(73)/2 times 4

Answer 12

u guys r awsome and smart ... im not thx for u guys help

Answer 13

drop a perpendicular down the center and you get 8 for the height of the pyramid.

measure over 3 from there to get a triangle of:

8^2 + 3^2 = r^2

and r is the "height" you use to figure for the face triangles.

r = sqrt(64 +9) = sqrt(73)

sqrt(73) times 6 for the base divided by 2 gives the area of 1 face.

times that by 4 to get all the faces.

include the bottom if need be :) 6*6 = 36
