there are many rectangular prisms we can build to fit this criteria. you have to be more specific as to how you want the measurements of the side to relate to each other. if, for instance, you could give us any two measurements, we could find the third. say you give the length and width (within reason), we can tell you what the height has to be to have a surface area of 9 in^2 , etc

this means we have to make a cylindrical package with a volume of at least 36 in^3 (i say at least because we may have to account for the extra spaces between the gummy bears when they are put into the package. you will need two circular disks and a rectangle sheet to build this container. again, more info is needed before we give you exact measurements.

then i have to make a cylindrical package that holds 150 gummy bears when each gummy bear is .24 in cubed. i need again side lengths and what i need to build it.

again, give us something to work with. tell us the height that you want the pyramid to be, and we will show you how to find the length of all the sides or vice versa.last one i need a regular hexagonal pyramid with a volume of 196 cm squared. and i need the base size and side lengths.

you already have the formulas, now you need to figure out the measurements. plug in the values in the formula that you must have. then plug in all the values except one as you would like them to be, then solve for the last one.

if you could show me how the math is, like how to work it out, so i can know how to do this stuff...

PS. double posting the same question is against the rules here, please ask your question onceFormulas:

Prism

Lateral Area: perimiter(height)

Surface Area: 2(base) + Lateral Area

Volume: Base(Height)

cylinder

Lateral Area: circomference(height)

Surface Area: 2(base) + lateral area

Volume: base(height)

pyramids

Lateral Area: 1/2 perimeter (slant height)

Surface Area: Base + lateral area

Volume: 1/3 base (height)

area of a regular polygon: 1/2 apothem (peremeter)
