Question

1. marta has a cube that she wants to paint. she needs to find the surface area to determine the amount of paint she needs. she draws the following net to help her find the surface area of the cube. what is the surface area of the cube? work: sa is 6x# on a square 8x6=48 the sa is 48

Explanation:

Step1: Recall surface - area formula

The surface - area formula for a cube is $SA = 6s^{2}$, where $s$ is the side - length of the cube.

Step2: Identify side - length

The side - length of the cube $s = 8$ cm, as given in the problem.

Step3: Calculate surface area

Substitute $s = 8$ into the formula: $SA=6\times8^{2}=6\times64 = 384$ $cm^{2}$.

Answer:

$384$ $cm^{2}$
