Answer: The total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.
Step-by-step explanation:
Volume of sphere :-
, where r is the radius of the sphere.
Given : Diameter of the bubble = 0.01 m
Then Radius of the bubble = 
Volume of each bubble:-

Also, Number of bubbles in each sheet = 1,000,000
Then , the total volume of air contained in the bubbles of one sheet of bubble wrap will be :-

Hence, the total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.
I think it's a ruler mate.
The first one. The sum of all angles on a triangle is always equal to 180
180.
4•9=36, and 36•9 is 324. 4•3 is 12, while 12•12 is 144.
324 - 144 = 180. I hope this helps!
It subtracts 2 then adds 5
