If a cuboid of width and height-8m with a volume of 896m^3, work out the length of the cuboid and distance between two opposite points

Length=L 896= 8x8xL => L=896/64 => L=14
Distance between two opposite points = 3D TrigD=sqrt(8^2+8^2+14^2) =sqrt(324) =18

Show that (x-2) is a factor of 3x^3 -8x^2 +3x+2

The factor theorem states that a polynomial f(x) has a factor (x-k) if and only if f(k)=0.
f(2) = 3(2)^3 - 8(2)^2 + 3(2) + 2 = 3(8) - 8(4) + 6 + 2 = 24 - 32 + 8 = 0.
==> (x-2) is a fac...
