???????????? kongruent sides ???????????
???? yu meen all sides hav same length ????????
????? wot cha meen bi "side" ???...the line tween 2 faeses ?????
rektangel, so it must be square, side leng=7
so rim length=4*7=28
"prism" impli its a pryamid with 4 triangel sides
base=7
need tu get the "slant hite" av 1 faes
me thank yer werds impli the edj that go up from ground tu the point at top is 7
that meen the side av isosoleez triangel=7, so its equilateral triangel
base angel=60 deg
hite=7*sine(60 deg)=0.866025403
area av 1 faes=(1/2)base*hite=(1/2)*7*7*0.866025403
=21.21762239
area av 4 faeses=84.87
