Answer 1

where is the question?

Answer 2

nvm

Answer 3

What formula would I use?

Answer 4

@jhonyy9

Answer 5

Surface area= BasexBase+2BasexHeight+2BasexHeight

Answer 6

Alright. 1467.2?

Answer 7

@akihikokayaba are you sure ?

base *base -area of base
and there are 4 sides triangular so with area base *heigth /2 - so what me

Answer 8

ahemm how did you get 1467.2 anyway?

Answer 9

so what mean 4*(base*heigth/2) = 2*base*heigth so not how you have wrote there 2+2
- i think this is the right way - @jdoe0001 ?

Answer 10

804.4

Answer 11

4*(18*14*9/2)=536.4
2*20*14.2=568
804.4

Answer 12

@shaleiah attention there are two plus two different triangular sides
do you see it ?

Answer 13

yes

Answer 14

area of base = 18*20 = ?
area 2 sides = 2*18*14,9/2 +2*20*14,2/2 = ?

Answer 15

sorry the second line mean area of 2+2 sides

Answer 16

360 +
268,2
284

?

Answer 17

912.2

Answer 18

you have got it ?

Answer 19

yes - right sure

Answer 20

Yes, the surface area will be 912.2.

Answer 21

@mathmath333

Answer 22

yes

Answer 23

but this is a cylinder

Answer 24

example if u open up a can of pepsi it will be like rectangle so u have to find the area of rectangle + 2* area of circle

Answer 25

I got 880

Answer 26

total surface area of cylinder =\(\Large 2*\pi r^{2}+2\pi rh\)

Answer 27

r=20,h=20

Answer 28

3312 :)!

Answer 29

i m getting 5026

Answer 30

You're correct. I put 3.14 in my calculator instead of the pi symbol.... i got 5026.5 :)
