P is perimeter of base, and B is area of base?

5. helpmeplz311

yes

6. AriPotta

so what's the first figure?

7. helpmeplz311

8. omnomnom

Hm.. I am doing geometry right now.. do you mind waiting?

9. helpmeplz311

ill wait:) and hi:)

10. AriPotta

the figure with the 1 next to it

11. AriPotta

this second link i think. it has a 1 next to it, so i thought you'd want to go in order lol

12. helpmeplz311

umm, i think, is there such as thing as a square prism? or is it rectangular?

13. AriPotta

a "square prism" would be a cube lol. but yes, it is a rectangular prism

14. helpmeplz311

oh ok sorry

15. helpmeplz311

now what?

16. AriPotta

well, what's the perimeter of the base?

17. helpmeplz311

17 + 11 + 17 +11?

18. AriPotta

yes

19. helpmeplz311

mk, let me calculate

20. helpmeplz311

56

21. AriPotta

yep. now, what's the area of the base?

22. helpmeplz311

umm, 17 times 11?

23. helpmeplz311

no i mean 17 times 12!

24. AriPotta

yes

25. AriPotta

17 times 11

26. helpmeplz311

nvm nvm 11 times 12

27. helpmeplz311

oh srry

28. AriPotta

lol. you were right the first time

29. helpmeplz311

yes, sorry, im pretty dumb brb calculating...

30. helpmeplz311

187

31. helpmeplz311

umm, what if ni do them and u check them? ill brb,yes?

32. helpmeplz311

ill give thm a shot

33. AriPotta

ok

34. helpmeplz311

ok, brb.

35. helpmeplz311

but dont leave

36. omnomnom

O.O

37. omnomnom

Just finished my geometry.. But sorry Rachel i cant help with this one.. i have alot more hw today then i did the other days :( Sorry

38. mark_o.

he is painting 4 building 1 building will have a rectangular area =(50x25) sq yd but there are 4 rectangular area A1=4(50x25) sq yd= ? is it = 5000 sq yd? yes ? and the top portion of area A2=25x20=? ...sq yd is it= 500 sq yd. yes? if yes add the two areas together A1+A2=---- ?...sq yd

39. mark_o.

now for 4 building mult the area (A1+A2) by 4

40. mark_o.

@ helpmeplz311 bonus prob P=perimeter, P1=perimeter of P!, P2= perimeter of P2 P1=5+5+5+5=20 P2=10+10+4+4=28 B=bases, B!=area of base 1, B2=area of base 2 B1=5x5=25 B2=4x10=40 lateral surface area S= s(P!+P2)/2 lateral SA=6(20)(28)/2 =144 sq km ? is it? total SA=lateral SA + B1 +B2 = 144 +25 + 40 ? sq km is it? yes or no?

41. mark_o.

bonus was frustum of a pyramid

42. mark_o.

fig 1) rectangular prism perimeter P=2L+2W, L=length,W=width P=2*17 +2*11= 56 ? yes or no base area B=LW =17*11=187 ?yes or no lateral SA=P h=56*12=672 ?yes or no ,, h=height total SA =lateral SA +2B=672+2(187)=1046? yes or no?

43. mark_o.

fig 4) is the same as fig1) cube ,, except L=W=H perimeter P=2L+2W, L=length,W=width, note L=W=3.5 P=2(L+W) P=2(3.5+3.5)=14 ? base area B=LW =3.5x3.5=12.25? lateral SA=P h=14x3.5=49? total SA=2LW + 2(L+W)h=2(3.5)(3.5) + 2(3.5+3.5)3.5=73.5?
