A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight
2.2 in.
2 in.
1.7 in.

(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

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

1.) 21

2.) 0.453

3.) 1.5

4.) 48

5.) $ 22
