Question

The side of cube is 1.1cm find its total surface area ​

Answer 1

Answer:

7.26 cm^2

Step-by-step explanation:

Side of cube, a = 1.1 cm

Total surface area of a cube= $6a^{2}$

                                              = 6* 1.1* 1.1

                                              = 6* 1.21

                                              = 7.26 $cm^{2}$ or 0.000726 $m^{2}$

                                                 [1 $cm^{2}$ = 0.0001 $m^{2}$]

Answer 2

Answer:

7.26cm2

Step-by-step explanation:

total surface area of cube = 6 a2

a= 1.1 = 6 x 1.1 x 1.1

= 7.26 cm2
