Help? I really need to get this done :/

Cinema Threaters created a new popcorn box in the shape of a rectangular prism. The new popcorn box has a length of 6 inches, a width of 3.5 inches and a height of 3.5 inches but does not include a lid.

1. How much material is needed to create the box?
2. How much popcorn does the box hold?
(Attachment is the box)

Respuesta :

so surface area minus top
so we have 4 sides and 2 of them are equal area
they area
legntht iems height
and
width times hiehgt
then the bottom is legntht iems width

so surface area is
2(lh)+2(wh)+(lw)

the surface are is the amount of material needed

L=6
W=3.5
H=3.5
subsitute
2(lh)+2(wh)+(lw)
2(6 times 3.5)+2(3.5 times 3.5)+(6 times 3.5)
2(21)+2(12.25)+(21)
42+24.5+21
87.5


87.5 in^2 of material



how much volume means
legnth times widh titme height
6 times 3.5 times 3.5
73.5 in^3






1. 87.5 in^2 of material
2. 73.5 in^3 is volume
