Make a guess.
Orange is about 1.5 inch radius sphere so the volume is,
V=%284%2F3%29pi%2AR%5E3=%284%2F3%29pi%283%2F2%29%5E3=%289%2F2%29piin%5E3
.
.
.
TP roll (check your spelling) is about 5 in diameter with a 1 inch hollow center and about 6 inches tall.
Using the volume of a cylinder,
V=pi%2A%28R%5B2%5D-R%5B1%5D%29%5E2%2AH
V=pi%2A%28%285%2F2%29%5E2-%281%2F2%29%5E2%29%2A6
V=pi%2A%2825%2F4-1%2F4%29%2A6
V=36piin%5E3
