Just do 18 divided by 6, and make your answer a negative. The answer is -3
It would be 7x7 + 2x2 = 53
Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
I hope this helps you
68,25=(9+12).h/2
2.68,25=21.h
136,5/21=h
h=6,5
It’s a!!!!!!!!!!!!!!!!!!!!!!!!
