Question

find the surface area of the cube using the net. find the area of one square. one square: ? cm² all squares × 6 surface area: cm²

Explanation:

Step1: Calculate area of one square

The area of a square is $A = s^2$, where $s = 6$ cm. So $A=6\times6$.
$A = 36$ cm²

Step2: Calculate surface - area of cube

A cube has 6 equal - sized faces. Since the area of one face is 36 cm², the surface area $S$ of the cube is $S=6\times A$.
$S = 6\times36=216$ cm²

Answer:

One square: 36 cm²
Surface area: 216 cm²
