1 Let its height be 5x and its width be 3x2 So: 5x*3x*21 = 2835 => 315x2 = 2835 cubic cm3 Divide both sides by 315 and then square root both sides4 Then: x = 3 so then height is 5*3 = 15 cm and width is 3*3 = 9cm5 Surface area: (2*15*9)+(2*15*21)+(2*9*21) = 1278 square cm6 Check: 15*9*21 = 2835 cubic cm
