Answer 2

what is lateral area?

Answer 3

use these formulas

Lateral Surface Area: LSA = 2*(LH + WH)

Total Surface Area: SA = 2*(LH + WH + LW)

where in this case

L = 19
W = 6
H = 2

Answer 4

The sum of the areas of the lateral (vertical) faces of a cylinder, cone, frustum, or the like; A particular part of the medulla...

Answer 5

you put some together, like L and H? For that, would i just put 192?

Answer 6

multiply them together

Answer 7

LH means L times H

Answer 8

and "2 *" means " 2 x"?

Answer 9

correct

2*

means

2 times ...

Answer 10

example:

2*5 = 2 times 5 = 10

Answer 11

kay. just checking lol

Answer 12

that's good you asked

Answer 13

Do I do the same thing for this one?

Answer 14

Answer 15

if you let

a = length of leg #1
b = length of leg #2
c = length of hypotenuse
h = height of prism

then

Lateral Surface Area: LSA = 2*(ah+bh+ch)

Total Surface Area: SA = 2*(ah+bh+ch) + ab

Answer 16

which is leg number 1 and 2? :/

Answer 17

either one works

Answer 18

a = 2
b = 5

or

a = 5
b = 2

Answer 19

which on is h?

Answer 20

is it 26?

Answer 21

yes

Answer 22

one*

Answer 23

thanks (:

Answer 24

yw

Answer 25

um, i didn't get the right answer

Answer 26

what did you get

Answer 27

oh wait, I doubled everything when I shouldn't have..my bad

it should be this

Lateral Surface Area: LSA = ah+bh+ch

Total Surface Area: SA = ah+bh+ch + ab
