OpenStudy (imnotgoodatmath):

what grade you in?

OpenStudy (anonymous):

7th

OpenStudy (imnotgoodatmath):

yeah, i got this homie :D

OpenStudy (imnotgoodatmath):

Well, for it to be similar I would say to just apply the change to one side of the box to all sides of the box. i.e. 2ft went to 6ft (which is multiplying it by 3). I would just multiply the other 2 sides by 3 to get the length of the other 2 sides.

OpenStudy (imnotgoodatmath):

2×3=6 0.5×3=? 1×3=? Just scaling all sides by 3. As they have done with the one given side. This will give the box a similar shape but it will be larger in all dimensions.

OpenStudy (anonymous):

so do i add all my answers up? like 6 plus 1.5 plus 3?

OpenStudy (imnotgoodatmath):

That will give you the dimensions of the larger box. Do you know the formula for the volume of that shape?

OpenStudy (anonymous):

no

OpenStudy (imnotgoodatmath):

Volume=length×width×height

OpenStudy (anonymous):

wait, can you help with another?

Mario Agnello is opening a new pizza shop in town. He plans to offer a twelve-inch diameter pizza and an eighteen-inch diameter pizza. He has set the price of a twelve-inch cheese pizza at eight dollars, based on the amount of ingredients needed to cover that size crust. If Mario would like to keep the pricing proportional, what should he charge for an eighteen-inch cheese pizza? Show and explain your solution.
