What is the current location of the submarine relative to the surface of the ocean? A submarine starts at the ocean's surface and then
descends at a speed of 24.75 feet per minute for
11 min. The submarine stays at that position for one
hour and then rises 65.75 ft.
O-206.5 ft
0-272.25 ft
O-338.0 ft
O-385.25 ft

(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

i think it would be 42cm
