Question

The Surface Area of Cube is 54 cm². Find the edge.

Answer 1

ANSWER

GIVEN

TSA of cube= 54cm²

we know the formula of total surface area of cube which is = 6× side²

=> 6× side² =54

=> side²=54/6

=> side²=9

=> side=√9

= side =3


THANKS

Answer 2

》 Surface area of cube is 54 cm².

We know that..

Surface area of cube = 6 × side²

We have to find the side.

So, put the known values in above formula.

=> 54 = 6 × side²

=> 54/6 = side²

=> 9 = side²

=> side² = 9

=> side = $\sqrt{9}$

=> side = 3 cm

_____________________________

Side of cube 3 cm.

☆ VERIFICATION :

From above calculations we have side = 3 cm.

Put that value in : 54 = 6 × side²

=> 54 = 6 (3)²

=> 54 = 6 (9)

=> 54 = 54
