Answer:

i) side = 12cm

ii) LSA = 576cm²

ii) Volume =  1728cm³

Step-by-step explanation:

TSA of a cube = 6a²

864cm² = 6a²

864/6

144 = a²

\sqrt{144} = a

12cm = a          We found that side is 12cm

LSA = 4a² (put the value of side we found in this equation)

       = 4 x 12 x 12 = 576cm²

Volume =  a³

             = 12 × 12× 12 = 1728cm³
