Density of any object of found by dividing its Mass by its Volume
So firstly we have to find the Volume
Volume of sphere = 
where r is radius
So lets find the Volume
Volume of spherical marble = 
= 
Now mass = 10 grams
So density = Mass/Volume =
rho
≈2.39 rho
B+g=33
b=g+5
G+5+g=33
2g+38
G=14
B+14=33
B=19
There are 14 girls and 19 boys
Area of cake: 15 x 15 = 225 square inches
piece of cake: 2 1/5 x 2 1/5 = 4.84 square inches
225 / 4.84 = 46.49
so 46 whole pieces can be cut
