The surface area of the three cubes is 24 square cm, 54 square cm, 294 square cm. The three cubes are fused into a large cube to obtain a large volume

The surface area of the three cubes is 24 square cm, 54 square cm, 294 square cm. The three cubes are fused into a large cube to obtain a large volume

24 / 6 = 4 cm 2
Side length = 2cm
Volume = 2 * 2 * 2 = 8 cc
54 / 6 = 9 square centimeters
Side length = 3cm
Volume = 3 * 3 * 3 = 27 CC
294 / 6 = 49 square centimeters
Side length = 7cm
Volume = 7 * 7 * 7 = 343cm
Large volume = 8 + 27 + 343 = 378 CC
