Question 1126575: A jumbo chocolate bar with a rectangular shape measures 12 cm in length, 7 cm in width, and 3 cm in thickness. Due to escalating costs of cocoa, management decides to reduce the volume of the bar by 10%. To accomplish this reduction, management decides the new bar should have the same 3 cm thickness, but the length and width each should be reduced an equal number of cm.
