The volume of a rectangular prism is found with the formula V = w · l · h So if you substitute those variables for the dimensions of the prism you get V = 5 · 4 · 7 Then you simplify V = 20 · 7 V = 140
Therefore, the volume of the prism is answer choice 1, 140 meters³
It would be 37.5 times, which rounded up would be about 38 because blue would be .25 of the spinner, so you would expect it to land on blue 25% of the time. Hope this helps!!
