$\Large\fbox{\color{purple}{ SOLUTION }}$

$\Large\mathcal\purple{CUBOID}$

$\implies \: lsa = 2(l + b)h \\ \\ \: \implies \: tsa = 2(lb + bl + hl) \\ \\ \implies \: volume \: = l \times b \times h$

$\Large\mathcal\blue{CUBE}$

$\implies \: lsa = {4a}^{2} \\ \\ \implies \: tsa = {6a}^{2} \\ \\ \implies \: volume = {a}^{3}$

Answer 2

Step-by-step explanation:

$formula \: \: \: \: \: \: \: \: cube \: \: \: \: \: \: \: \: cubid \\ = surface \: \: \: \: \: \: \: \: 6 { l }^{2} \: \: \: \: \: \: \: \: 2(lb + bh)\\ area \\ =lateral \: \: \: \: \: \: \: \: \: 4 l^{2} \: \: \: \: \: \: \: \: \: 2h(l + b) \\ surface \: area \\ = volume \: \: \: \: \: \: \: \: \: {l}^{3} \: \: \: \: \: \: \: \: \: l \times b \times h \\ = diogonal \: \: \: \: \: \sqrt{3l } \: \: \: \: \: \sqrt{(l ^{2} + {b}^{2} + {h}^{2}) }$
