VbhHVVVV​=21​bhH=4=3=10=21​(4)(3)(10)=21​12(10)=21​120=60​The prism's volume is 60 in 3.Knowing the volume of the prism, we can proceed to solve for how many jelly beans will fill it. We know that 20 jelly beans fill 25 in ∧3 of space, so we can set up a proportion to solve for how many jelly beans fill 60 in 3 of space:25 in 320 jelly beans ​=60 in 3x jelly beans ​To solve, we need to cross-multiply and solve for x :​1200=25x251200​=xx=48​Approximately 48 jelly beans would fit in the prism described, so A is the correct answer.
