Answer 1

help plzz

Answer 2

plzzzz

Answer 3

thanks so much

Answer 4

Surface area is finding the area of each face.

It's analogous to gift wrapping a box

Answer 5

Her answer is wrong, by the way.

Answer 6

oh can you help me then

Answer 7

So to find the surface area, we just have to find the area of the square and the triangles and add them all up.

What is the formula for the area of a square?
And the area of a triangle?

Answer 8

idek im so dum

Answer 9

have you ever seen this formula

area of a square = side * side

Answer 10

no

Answer 11

:(

Answer 12

so the area of a square is side times side

what is the length of the side in the image they gave you?

Answer 13

7 I think

Answer 14

Yes... you already shared the image earlier. What is the length of one side of the square?

Do you know what a square is?

Answer 15

yes, that's good

Answer 16

So area = side * side

you said that the side is 7

area = 7 * 7

what is 7*7 = ?

Answer 17

Just multiply the numbers @tiktokstar

Answer 18

ik 1 sec

Answer 19

49?

Answer 20

Good.

Now the area of a triangle = 1/2 * base * height


What is the base and what is the height?

Answer 21

can you just tell me the answer

Answer 22

Answer 27

oh ok sorry

Answer 28

Yeah, I know we all want the answer so we can move on. But if we don't learn how to do it on our own, we won't make it very far.

Look at the triangle I drew and look at the triangle in your image. What is the length of the base of the triangle?

Hint: It's the same length as the side of the square because the base of the triangle is right next to it

Answer 29

is it 14?

Answer 30

That would be the height.

What's the other number we have? That's our base.

We need both numbers to plug into the formula for area
