The cooler measurement should be measured in cm cubed, because you are finding the volume, which is three dimensional. The volume of the figure is 180 cm cubed. If you multiply the width, length, and height of the top object you get 36. When you add that to the volume of the bottom one (144) you get 180 cm cubed.
Answer:
3(19x -y + 2z) is equivalent to the equation above
It should be two if this is pre calc.
The sample space would be 27. The probability of getting 3 heads if you flip 3 pennies is 1/27.
Hope it helps! :)
