Answer:
110
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
Answer:
wait what, what grade are u even in?? I barely understand this I'm in freaking 8th grade this is high school!
G=3M
G+M=56
-------------------------------------------
3M+M=56
4M=56
M=56/4=14
---------------------------------------------
G+14=56
G=42
---------------------------------------------
So Gabriel is 42 and Mikhail is 14.
