Question

What is the surface area of the regular pyramid below?

Answer 1

@ganeshie8 really need help

Answer 2

Would you like the answer? or an explanation?

Answer 3

if you can give me both?

Answer 4

Your in 3D meanings correct?

Answer 5

i believe so :(

Answer 6

Hold on, I have lots of sticky notes for my equations and formulas, is this conections?

Answer 7

what do you mean connections?

Answer 8

Connections accademy, are you not?

Answer 9

Forget it, anyway; Here is the formula
((base x height ÷ 2) x height*) ÷ 3
*this height is the height of the prism

Answer 10

oh no im just taking some classes online sorry about that

Answer 11

So according to your image posted... The base is 14, and the height is 20, correct?

Answer 12

yes

Answer 13

Oh, wait! My bad, you said find the area! Okay Soooorry, correct formula coming up ><

Answer 14

Okay, so what do you know of finding surface areas?

Answer 15

really nothing i just been lucky to find the answers for other ones on the internet

Answer 16

Area of Base(A) = ½ * a * s
Surface Area of Pyramid = (½ * a * s) + ((3/2)sl) = A + ((3/2)sl)
Volume of Pyramid = (1/6)abh ||| a = apothem length, s,b = side, h = height and l = slant height

Answer 17

can you plug it in for me?

Answer 18

(½ * a * s) = 140

Answer 19

1/2 * 20 *14=120

Answer 20

No because you have to use 0.5 instead of 1/2

Answer 21

0.5*20*14=140

Answer 22

Okay, I'm confusing myself on this easy one, so heres the easiest formula; [Base Area] + 1/2 × Perimeter × [Slant Length]

Answer 23

okay just the answer lol

Answer 24

Okay hold on, working on it ><

Answer 25

Okay so I cant quite get it rolling, but I think it may be B

Answer 26

WAIT

Answer 27
