To solve this problem, we use the formula given, which states that SA=6s^2, where SA is the surface area and s is the edge length of the cube.
We were given that the edge length of the cube is 3 1/2 feet, and that we are trying to find the surface area of the cube, so let’s plug these values into our formula.
SA=6(3 1/2)^2
To make this easier to simplify, we are going to replace 3 1/2 with its equal improper fraction, 7/2.
SA=6(7/2)^2
Now, following the order of operations, we are going to simplify what is inside the parenthesis by squaring it.
SA=6(49/4)
Now, we are going to multiply our last two terms together, to get:
SA= 294/4
This number simplifies to 147/2 when we divide both the numerator and denominator by their greatest common factor of 2.
However, the problem asks for your answer as a mixed number in simplest form, which we get when we divide out this improper fraction.
Your final answer is 73 1/2 ft^2.
I hope this helps!
12 yd
You can use what you are provided with the 7 day and 5 yd which equal the side that is missing
7+5 =12
Answer:
104
Step-by-step explanation:
232-128=104
The GCF is the biggest number that goes into all of the terms. The biggest coefficient for x and y multiplied together. The GCF in these answers is to the left of the parenthesis.
If you multiply the GCF into he parenthesis you will get the original equation. On the other hand, the biggest number that goes into all of the terms is 3x * 1y = 3xy
Now you know the GCF, multiply it out in both of those answers and pick the one that is the original equation
