You have two block of clay in cube form and the edges are 10 cm. How many spheres with a radius of 5 cm can you make with that amount of clay?

Question

anonymous · Answer

Volume of sphere = (4/3)pi*r^3

anonymous · Answer

Volume of cube = a^3 where a is the side of the cube

anonymous · Answer

So. The answer is 3?

callisto · Answer

volume of cubes available = 10^3 x2= 2000 cm^3
volume of each sphere = 4/3 (pi) (5)^3 = 523.59878cm^3
no. of sphere can be made = 2000/523.59878 = 3.81, that is 3 spheres can be made

anonymous · Answer

So, 3 is right. @Callisto  You know, you could of just said that, but thanks anyway.
