Question

What is the surface area of the cube below?A 150 unitsB. 300 unitsC. 50 unitsO 0.75 units

Answer 1

The formula for the surface area S of a cube can be writte as;

`S=6l^2`

Where;

`l\text{ is the side length of the cube}`

From the attached image, the length of the side of the given cube is 5 units.

`l=\text{ 5 units}`

So, the surface area can be calculated by substituting the value of the length into the formula.

`\begin{gathered} S=6l^{2\text{ }}=6(5)^2 \\ S\text{ = 6}*25 \\ S=150units^2 \\ \end{gathered}`

Therefore, the surface area of the cube
