Answer the following. Look at the cuboid. .
cm
What is the surface area of the box?
Somm
15cm
cm2

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

(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

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer: 48
