Answer:
25) 432 cubic inches
26) 408 cubic inches
27) 6 sides
Explanation:
25) you have to multiply 6 by 4 and by 18 or 6×4×18= 432 cubic inches and not square due to the box is a rectangular.
26) Surface area you have to use the equation of 2(lw+lh+wh) -> 2(18*4+18*6+4*6)
w=width(4)
h= height(6)
l= length(18)
Once plugged in you get 408 cubic inches
27) A box has 6 faces due to the fact that any cube, rectangle, or box will have a net of 6 faces.
