8c1p28) Grains of fine California beach sand are approximately spheres with an average radius of 38 μ m and are made of silicon dioxide. A solid cube of silicon dioxide with a volume of 1.00 m3 has a mass of 2600 kg. What mass of small sand grains would have a total surface area (the total area of all individual spheres) equal to the surface area of a cube 1.00 m on an edge?

What is the surface area of your cube?

What is the surface area of each grain?

How many grains do you need to equal the surface area of the cube?

What is the volume of one grain?

What is the volume of the number of grains you calculated earlier?

What is the mass of that many grains?

If you follow these steps, you should have your answer.

If you have any problems, please feel free to ask.
