Answer: the associative property of addition
Step-by-step explanation: when adding three or more terms, you can combine the middle terms with either the first term or the last term and as you add the results, the sum will be the same either way.
The surface area would be 150cm and the volume would be 125cm. To get volume you do 5 cubed to get the answer 125. To get surface area you would do 5 multiplied by 5 multiplied by the cubes 6 sides to get 150.
<u>Answer</u>:

<u>Explanation</u>:
Given:
Height at which the sand bag is released from the hot air balloon
To find:
Time taken for the sandbag to hit the ground, t =?
Solution:
The initial height =s
Initially the height will be 0
Hence
the falling object model equation

Substituting the values we get,






Result:
Thus it takes 5 seconds for the sandbag to hit the ground
