Answer:
Hey mate! Here's your answer
Step-by-step explanation:
volume of new cube = sum of volumes of three old cubes
volume of 1st cube =
a = 12 cm
a^3 = 12 x 12 x 12 = 1728 cm^3
volume of 2nd cube =
a = 16 cm
a^3 = 16 x 16 x 16 = 4096 cm^3
volume of 3rd cube =
a = 20 cm
a^3 = 20 x 20 x 20 = 8000 cm^3
volume of newly formed cube = 1728 + 4096 + 8000 = 13824 cm^3
a^3 = 13824 cm
a = 3√13824 = 24cm
