find volume of each
volume of a sphere is 4/3 times pi times radius^3
so first calculate the smaler sphere
radius=6
pi is aprox 3.14
4/3 times 3.14 times r^3
4/3 times 3.14 times 6^3
4/3 times 3.14 times 216
904.32 cm^3=volume
volume of larger
radius=24
4/3 times 3.14 times 24^3
4/3 times 3.14 times 13824
57876.48 cm^3
so then subtract the volume of the smaller sphere from the larger sphere
57876.48-904.32=56972.16 cm
he used
56972.16 cm^3 plaster
I think you mean to the hundreth's place which is the place denoted by the x in 0.0x so it is to the hundreth's place
