we are given the h = w

Answer 4

do you know how to find the volume of a rectangular prism?

Answer 5

V=LWH

Answer 6

good, and since w=h lets say:

V = LW^2

Answer 7

we know V = 54 soo

54 = LW^2

and it says L = 2*W

Answer 8

54 = 2WWW = 2W^3 then right?

Answer 9

solve for W and you will have the means to get the other measures

W = W

H = W

L = 2W

Answer 10

ah .. i get it !

Answer 11

then ?
