Answer 1

It will take 401.88 cubic inches of water to fill the toys.

Explanation:

Given,

Radius of sphere shaped toy = 2 inches

We will find volume of the toy.

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

Volume of sphere shaped toy =
`(4)/(3)*3.14*(2)^3`

Volume of sphere shaped toy =
`(4)/(3)*3.14*8=(100.48)/(3)`

Volume of sphere shaped toy = 33.49 cubic inches

Number of toys = 12

Total volume = 12*33.49 = 401.88 cubic inches

It will take 401.88 cubic inches of water to fill the toys.
