How many square inches of a material is needed to create an open top rectangular solid whose volume is 54 cubic inches? Assume that the length and width are of the same measurement and that the height is twice the length.

Question

unklerhaukus · Answer

$$w=l=\frac h 2\qquad\qquad V=wlh\qquad\qquad  S=2(wl+wh+lh)$$

unklerhaukus · Answer

w=width, l=lenght, h=height,
V=volume, S=surface area

thank you :D

unklerhaukus · Answer

actually it is an open top so$$S=(wh+lh)$$

anonymous · Answer

let 54-volume
x-length
x-width
2x-height
54= L x W x H
54= (X)(X)(2X)
54=2x^3
x=3
distribute all of them : )

anonymous · Answer

S=((3)(3)+(3)(6))
S=9+18
S=27
