B^2-6b+8 turns into b^2-2b-4b+8 due to the sum product pattern. which then turns into b(b-2) - 4(b-2) and then its (b-4)(b-2)

Step-by-step explanation:
Formula for SA of a rectangular prism:
SA = 2lh + 2lw + 2wh
Given dimensions:
l = 1
w = 7
h = 6
Simply plug in these given dimensions into the SA formula to get the answer
SA = 2lh + 2lw + 2wh
Substitute given variables
SA = 2(1)(6) + 2(7)(1) + 2(6)(7)
* Multiply parentheses that are next to each other *
SA = 2(6) + 2(7) + 2(42)
* Multiply again *
SA = 12 + 14 + 84
*add*
SA = 110
Step-by-step explanation:
density =mass/Volume
but Si unit of volume is m3
convert 980000cm3 into m3 by dividing with 1000000= 980000/1000000= 0.098 m3
D= M/V = 65.8/0.098= 671.43 kg/m3
