Please help What do a cylinder and a cone have in common? How are they different? (Hint: Look up the formula for the volume of a cone.)

Similarities:

Similarities are that these figures have curved surfaces, not flat faces. A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat. A cone has one circular base and a vertex that is not on the base.

Differences:

A cone is a 3-dimensional solid object that has a circular base and a single vertex. ... Cylinder : A cylinder is a 3-dimensional solid object that has two parallel circular base connected by a curved surface.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
