Answer with Step-by-step explanation:
Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)
Thus we have
1 mole of sand = sand particles
Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is
Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of trillion sand particles is
Part 2)
Since it is given that volume of 1 sand particle is thus the volume of 1 mole of sand is volume of sand particles
Thus volume of 1 mole is
Now since the Area of united states is
Thus the depth of the sand pile is

Answer:
7 times 7 times 7 times 7= 2401
Step-by-step explanation:
I think thats what its asking
Area of one big square = 1 square meter
Now the bigger square is divided into 9 smaller square
Area of 9 small squares = Area of 1 big square= 1 square meter
So applying unitary method we can find are of 1 small square.
Area of 1 small square = 1/9 square meter
Now each small square is divided into two identical triangles.
So ,
Area of 1 triangle = 1/2 of area of 1 small square =(1/2) (1/9) = 1/18 square meter
Again applying unitary method to find area of 6 triangles,
Area of 6 triangles = 6 * area of 1 triangle = 6 * (1/18) = 1/3 square meter
Answer : Area of 6 triangles is 1/3 square meters.
Answer:$9.29
Step-by-step explanation:For unit rate finding the value of one is the objective. Easiest way to find it is by dividing the value (the amount of money being payed) by the amount beig sold ( the 5 shirts) so basically $46.45 ÷ 5
