Answer:
Number 9 is C. 1,000 ft^3
Number 10 is B. 144 in^3
Step-by-step explanation:
For both number 9 and 10, we are trying to find volume. Volume is the space within a three dimensional shape. To find the volume you do length × width × height. Knowing this we can start solving.
For number 9, the length is 20 ft, the width is 10 ft and the height/depth is 5 ft. Now we multiply these numbers.
20*10*5 = 1,000
This gives of 1,000. Since this is in feet, we add feet/ft at the end. Also since it is volume, you add ^3
1,000 ft^3
Now lets do the same for number 10
The length is 6, the width is 2 and the height is 12. Now multiply
6*2*12 = 144
This one is in inches so we add inches/in at the end. It is also volume so we add ^3 as well
144 in^3
