Question

A cube has an edge length of one hakf in. which of the following is its surface area

Answer 1

Step 1

Write the parameters of a cube.

Length L = 1/2

Step 2

Write the formula for the surface area of a cube

$\text{Surface area = 6L}^2$

Step 3

Substitute the value of L and find the surface area.

$\begin{gathered} SurfaceArea=6L^2 \\ =\text{ 6 x (}\frac{1}{2})^2 \\ =\text{ 6 x}\frac{1}{4} \\ =\text{ }\frac{6}{4} \\ =\text{ }\frac{3}{2}in^2 \\ =\text{ 1}\frac{1}{2}in^2 \end{gathered}$
