Grains of fine California beach sand are approximately spheres with an average radius of 45 µm 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 sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.50 m on an edge?

answer is in kg

2. Relevant equations

volume of sphere=4/3*pi*r^3

3. The attempt at a solution
