Surface area so we see we got 2 triangles (top and bottom) and 3 sides they aer all height 6 we got that one is 3 the other is 3 and the back one is missing. how do we find it? oh, look, there is a right angle sign we have a right triangle legs are 3 and 3 and hyptonuse is ? 3^2+3^2=c^2 9+9=c^2 18=c^2 sqrt both sides 3√2=c
so the bases are 3 and 3 and 3√2
surfacare area
area of rectangle=legnth times width area of triangle=1/2 times base tiems height
so there are 2 top triangles that are 3 by 3 2*(1/2*3*3)=9 the top and bottom is total 9 sides 3*6=18 2 of them 18*2=36
