Question

what is A cube with an edge 9 cm in surface

Answer 1

Answer:

surface area formula of cube = 6s^2

= 6*(9)^2

= 6*(81)

= 486cm^2

Answer 2

${\red{\underline{\underline{\bold{Given:-}}}}}$

• Edge of cube = 9cm

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

• The surface area of the cube

${\green{\underline{\underline{\bold{Solution:-}}}}}$

Edge of cube = 9cm

Surface of cube = 6${s}^{2}$

= 6$({9}^{2})$

= 6 (81)

= 486${cm}^{2}$

________________

Formula used:-

• Surface area of cube = 6${s}^{2}$

${\pink{\underline{\underline{\bold{Additional \: Information:-}}}}}$

• Surface area of cuboid = 2(lb + bh + lh)

• Surface area of square = 4π${r}^{2}$

• Surface area of cylinder = 2πrh + 2${r}^{2}$
