Question

ANALYZE The surface area of a three-dimensional object is the sum of the area of the faces. If 1 represents the length of the side of a cube, waa formula for the surface area S of the cube

Answer 1

ANSWER

$6$

EXPLANATION

The length is represented by; 1

Recall that the formula for calculating the surface area of a cube is;

$6l^2$

Given that 1 represent the sides of the cube, hence substitute 1 equal to l in the formula above.

Therefore, the formula for the surface area S of the cube is;

$\begin{gathered} 6l^2 \\ 6\times1^2 \\ =6 \end{gathered}$
