Question

Find the total surface area of a cube whose volume is 27 cm​

Answer 1

Answer:

volume of cube = (side)³

(side)³= 27

side =√27

side = 3

Total surface area of cube = 6× (side )²

total surface area of cube = 6×3²

=6×9

Answer 2

Answer: Total surface area = 54 cm².

Step-by-step explanation:

Given : Volume of cube = 27 $cm^{3}$

To Find : Total surface area

Solution :

We know that,

Volume of cube = $side^{3}$

                           = 27

∴ Length of side = ∛27 = 3cm

∴ Total surface area of cube = 6* $side^{2}$

                                               = 6 * $3^{2}$

                                               = 54 $cm^{2}$
