SA means Surface area?

Answer 2

yes it does

Answer 3

Not so sure about this one but the regular trapezoid surface area is

Answer 14

You have to find the area of each side. There are 6 sides, so we need 6 numbers
They tell us the front side (and so also the back side) is a trapezoid with bases 4 and 6, and height 3

Answer 15

do you know how to find the area of a trapezoid ?

Answer 16

is the area 15? I know the formula is B1+B2)H/2

Answer 17

yes, 15. And the back is also 15
so we have 4 more sides to do.

Answer 18

and the rest are rectangles right? so you use B*H

Answer 19

yes

Answer 20

Okay one side is 14.4,one is 21, one is 12, and the back is 25.2

Answer 21

ok on the 25.2 and 21

I don't get 14.4 or 12

Answer 22

because it says 3.6 instead of 3

Answer 23

I think 3.6*7 is one side. that gives 25.2
(which is what you got)

I can see 3*4 =12 but that is a trapezoid figure , not a rectangle, so it's really 15

Answer 24

what do you get for the "bottom" and the "top" ?

Answer 25

15?

Answer 26

I am calling the "top" the side with the red 7 as one of its sides.

Answer 27

that would be 42

Answer 28

yes. and the side "opposite" (the "bottom" ) is ?
