Answer:
49
Step-by-step explanation:
Cube 7 to get the volume.(343)
Do 7^2 to get 49, then multiply by 6 to get the surface area(294)
Then subtract 343-294=49
By solving a linear equation we will see that the initial temperature was 66 degrees.
<h3>
What was the initial temperature?</h3>
Let's define T as the initial temperature.
First, it increases by 18 F, then it decreases 6 F, and finally, it increases another 12 F, such that the end temperature is 94F.
Then we can write:
T + 18F - 6F + 12F = 94F
Now we can solve that linear equation to find T.
T = 94F - 18F + 6F - 12 F = 66 F
In this way, we conclude that the initial temperature was 66 degrees.
