Step-by-step explanation: The solution is 52 cm². There are 6 faces on a rectangular prism and each face has a congruent match. Two faces have the dimensions 4 by 3, two faces have the dimensions 4 by 2 and 2 faces have the dimensions 3 by 2.
So 6 in.w x 4 inches in.h what will it be 30 inches wide
what we are doing right now is putting height over width, then the same thing to the other height over the width now we cross multiply (4) (30) = (6)(x) 120 = 6 x divide both sides by 6 to isolate the variable 20 = x The height of the poster, that has the width of 30 inches, will be 20 inches
