3. a rectangular prism has dimensions of 1/2 , 2, and 7/2 in.
(a) how many cubes with side lengths of 1 in. will fit into the prism? explain.
(b) how many cubes with side lengths of in. will fit into the prism? explain.

Ok
so

a. realisically, a cube with side length1 can't fit since 1>1/2 and the cube would stick out
but, if they wanted us to melt the cube or something
find volume of prism and divide that by th evolume of the cube

volume prism=1/2 times 2 times 7/2=7/2 cubic inches
volume cube=side^3=1^3=1
so
7/2/1=7/2
7/2 or 3.5 cubes can fit

b.
1/2 is the side lenght
so cuube volume1/2^3=1/8
(7/2)/(1/8)=(7/2)(8/1)=56/2=28
28 cubes can fit

10 will be the number of adult tickets and 11 will be the number of children tickets. i hope i could ! good luck : )

Ithink the answer is b
