Answer:
Step-by-step explanation:
Answer:
the correct answer is 3 times the difference of 62 and 42
It’s false because if you take a negative number away from another negative number it would give you another negative number not a positive number!
Step-by-step explanation:
To find the volume, you need to do length x width x height.
In this case, we are going to do 6 x 20 x 26.
You get 3,120 m^3.
