Part A:
So basically you use this formula to find the best-guessed height and length of the rectangular prism.
1029/7√=
147√=
12.12436
So the best-guessed height and length were both 12.12436.
Now take this info you learned from calculating the best-guessed height and length of the left prism. We are now going to use 12.12436 as the height and length for the right prism. Now make sure to use the order of operations rule "PEMDAS" to solve this equation. If you don't you will get the wrong answer.
12.12436(8)²=
147(8)=
1176
So the best-guessed volume of the right prism is 1176.
Part B:
So basically what you have to do is divide 1029 by the solution of height×width which will give you your length.
1029/(14×7)=
1029/98=
10.5
So the best-guessed length of the left prism is 10.5.
Now you will use this info to solve your problem
14×8×10.5= 1,008
1008/8√=
126√=
11.22497
So the best-guessed height would be 11.22497.
Part C:
I might need help with this part :)
