Answer» Step-by-step EXPLANATION: let length = 5x breadth = 4x HEIGHT = 2x TSA = 1216 Cm² now... TSA of cuboid = 2(lb+bh+hl) 1216 = 2(5x*4x +4x*2x* + 2x*5x) 1216 = 2(20x² + 8x² +10 x²) 1216 = 2(38x2) 1216 = 76 x² 1216/76 = x² 16 = x² 4 = x so.. length= 5x = 4*5 = 20 cm breadth = 4x = 4*4 = 16 cm height= 2x = 4*2 = 8cm 20*16*8 2560 cm³ thank you hope it HELPS ❤️❤️ plz mark it as brainliest |
