Find the volume of the figure above. 414 cm3

324 cm3

252 cm3

234 cm3

234

Step-by-step explanation:

Base can be divided on 2 rectangles : 4*4.5 and 9*(9 - 4.5).

Area base = 4*4.5 + 9*(9 - 4.5)

height prism = 4

Volume prism = Area base* height prism = [4*4.5 + 9*(9 - 4.5)] *4 = 234 cm³

c is the final answer! : )

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
