Question

what is the total surface of cube of 3 cm​

Answer 1

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{side = 3cm}$

$\: \: \: \: \: \: \: \: \: \: \: \: \sf{tsa \: of \: cube = 6 {a}^{2} }$

$= > \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6(3) {}^{2}$

$= > \: \: \: \: \: \: \: \: \: \: \: \: \: 6 \times 9$

$= > \: \: \: \: \: \: \: \: \: \: \: \: \sf{54 \: {cm}^{2} }$

Answer 2

Answer:

18 cm^2

Step-by-step explanation:

Given,

Side,a = 3cm

Total surface area of cube = 6a

TSA of cube = 6(3)

=18cm^2
