Question

Find the surface area of the cube.

Answer 1

Given:-

$\rightarrow$ Side(a) of the cube = $\sf{\frac{1}{3}ft}$.

To Find:-

$\rightarrow$ Surface Area of the cube with side $\sf{\frac{1}{3}ft.}$

Formula Used:-

$\rightarrow$ Surface area of cube = $\sf{6a^2}$

Solution:-

$\rightarrow$ Surface area of cube = $\sf{6a^2}$ (putting the value of a from the above given)

$\rightarrow$ $\sf{=\:6×(\frac{1}{3})^2}$

$\rightarrow$ $\sf{=\:6×\frac{1}{9}}$

$\rightarrow$ $\sf{=\:\frac{6}{9}}$

$\rightarrow$ $\sf{=\:\frac{2}{3}ft^2}$

Therefore, surface area of the given square = $\sf{=\:\frac{2}{3}ft^2}$

Answer 2

Answer:

Step-by-step explanation:

there are 6 square faces of a cube.

if side=x

surface area=6x²

=6(1/3)²

=6/9

=2/3 square foot
