A) To find the surface area of a cube, you have to use the formula 6•a^2
meaning you just have to calculate one side and multiply it by six.
541.5 is the surface area of the cube.
B) To find the surface area for just five sides, you'll be doing the same, except instead of 6 it'll be five.
so multiply 9.5 by itself
you get 90.25
Then you multiply 90.5 by 5
You get 451.25
Unfortunately I'm not sure how to do C. good luck
Yes it because any function can be a solution to any certain number of different systems
Answer:
when in doubt choose c
Step-by-step explanation:
Answer:
Percentage Error in counting the marbles in the jar is 39.72%
Step-by-step explanation:
Estimated marbles in the jar = 44
Actual marbles in the jar = 73
⇒Error in Marbles = Number of actual Marbles - Estimated marbles
= 73 - 44 = 29
So, the error in counting marbles in the jar is 29.
Now, 
= 
or, Percentage Error = 39.72%
Hence, the Percentage Error in counting the marbles in the jar is 39.72%
