Question

Using the formula above, find the surface area of a cube whise sides are all two thirds inches

Answer 1

Given:

The sides of the cube is, s=2/3 inches.

The objective is to find the surface area of cube.

The surface area can be calculated as,

`\begin{gathered} SA=6s^2 \\ =6((2)/(3))^2 \\ =6((4)/(9)) \\ =2.667in^2 \end{gathered}`

Hence, the surface area of the cube is 2.667 square inches.
