P is perimeter of base, and B is area of base?
so what's the first figure?
ummm on which link?
Hm.. I am doing geometry right now.. do you mind waiting?
ill wait:) and hi:)
the figure with the 1 next to it
this second link i think. it has a 1 next to it, so i thought you'd want to go in order lol
umm, i think, is there such as thing as a square prism? or is it rectangular?
a "square prism" would be a cube lol. but yes, it is a rectangular prism
oh ok sorry
well, what's the perimeter of the base?
17 + 11 + 17 +11?
mk, let me calculate
yep. now, what's the area of the base?
umm, 17 times 11?
no i mean 17 times 12!
17 times 11
nvm nvm 11 times 12
lol. you were right the first time
yes, sorry, im pretty dumb brb calculating...
umm, what if ni do them and u check them? ill brb,yes?
ill give thm a shot
but dont leave
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
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
now for 4 building mult the area (A1+A2) by 4
@ 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?
bonus was frustum of a pyramid
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?
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?
