Where is the Question? or am i just blind
(-43) x 7 x (-21) = 6,321
-3 + 7 = 4
4 - 7 = -3
I think that's what you want.
We know that it must equal 9, and that we do x•x-x+6 and find the square root
If you are looking for the surface area of the cube, it is 169. The equation for the surface area of a square is base times height. This would mean it’s 13x13 since all the sides are the same. 13x13=169
