Length x width x height. Plug in the numbers, the bottom one, the length is 5, width is 3, height is 9. 5 x 3 = 15. 15 x 9 = 135. Now considering you still have the top one to do, we can eliminate A, B, and C as answer choices. But if you want proof to solve it, the top figure is length 8 x width 3 x height 3. 8 x 3 = 24. 24 x 3 = 72. 135 + 72 = 207. Recap:
64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles. 64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours. =241 final answer
