$<b>$

(1) Find total surface area :-

Here we have edge of cube = 5 cm.

${TSA ~=~{6a}^{2}}$

$= 6 {(5)}^{2} {cm}^{2} \\ \\ = 6 \times 25 \\ \\ = 150 { \: cm}^{2}$

(2) Evaluate :-

Here we have to evaluate 4 - 3 .

Substract 3 from 4.

$= 4 - 3 \\ \\ = 1$

$\color{Red}{Answer~is~ {150 ~cm}^{2} and 1 }$.
