<span>Yes, this is the correct method. 10 in * (1 ft / 12 in) = 0.8333 ft, and the surface area of a cube is 6*s^2, where s is the edge length. Using s = 0.8333 in, I got a surface area of 4.17. If I used s = 0.833, I actually got 4.16, which is less accurate, so make sure you don't round too much when you do your calculations. XD

But I hope this helps!</span>

Valentin [98]

Answer:

8.4 dollars

Step-by-step explanation:

The error is in the resolution of the proportion. In fact, the initial proportion is correct:

$\frac{5}{3.5}=\frac{12}{x}$

where x is the total cost. However, the following step of the resolution is wrong. In fact, the correct resolution is the following:

- Multiplying by x on both sides:

$\frac{5x}{3.5}=12$

- Multiplying by 3.5 no both sides:

$5 x = 12 \cdot 3.5 \\5x = 42$

And now we can find x:

$x=\frac{42}{5}=8.4$

So, the total cost is 8.4 dollars.

368 spaces now, why?
There are 22 spaces per row, and we know there are 8 rows, so thats 176 spaces last month,
we add 4 spaces to each row of 22, thats 26 spaces per row, 26 * 8 = 368 total spaces
