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 (}(1)/(2))^2 \\ =\text{ 6 x}(1)/(4) \\ =\text{ }(6)/(4) \\ =\text{ }(3)/(2)in^2 \\ =\text{ 1}(1)/(2)in^2 \end{gathered}`
