Help please I just need the surface areas ill give 15 points. Answers only Please

I might not be able to answer all of these but here we go,

Step-by-step explanation:

#1

2 x 7 = 14 (14 + 14, ‘cause there’s two faces) 28

8 x 7 = 56 + 56 = 112

2 x 8 = 16 + 16 = 32

32 + 28 + 112 = 17

Add these bad boys together and ya get 189 babe.

#2  

4.8 x 7.2 / 2 = 17.28

17.28 + 17.28 = 34.56

7.2 x 10 = 72 + 72 = 144

6 x 10 = 60 + 60 = 120

Add em’ all together and ya get 315.84

And that’s all I can get for ya toots, because won’t let me take any longer to figure em’ out. Sorry babe, but I hope it helped. And no I don’t want points, don’t give me em’. Toodles baby~

1.     172 m ²

2.    226.56 m ²

3.    336 cm ²

4.    296 inch ²

5.    461 cm ²  wrapping paper

Step-by-step explanation:

1.   32+112+28 = 172 m ²    

2.   120+ 72 + 34.56 = 226.56 m ²    

(half base 3.6 x 4.8 = 17.28 x 2 = 34.56)

3.  Triangle face 48/2 = 24cm  x 2 = 48 = 48 +72+96+120 = 336 cm ²

4.  9x3 = 27  3x 10 = 30 9x 10 = 90  90+30+27 = 147   147 x 2 = 296 inch ²

5. Right Angle face Triangular prism

1/2 10.5 x 10 = 1/2 105 = 52,5

x2  = 105cm ²

10.5 x 8 = 120c

x2 = 240 cm ²

8x14.5 = 116cm

105+240+116 = 461 cm²
