576 because the triangle in the pyramid would be 216 divided by 2 is 108 since there is 4 triangles to a pyramid you multiply by 4 and that is 432. Then you add the area of the square which is 144 and add that to 432 which makes it 576
We can set it up like this:
This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours. To solve, we can use cross-multiplication:
It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.
36+18x
18x=-36
x=-2
coefficient of x is -2
