Question

what is the surface area of the cube? 12 mm 12 mm 12 mm square millimeters submit

Explanation:

Step1: Recall the formula for the surface area of a cube

The surface area \( SA \) of a cube is given by the formula \( SA = 6s^2 \), where \( s \) is the length of one side of the cube.

Step2: Identify the side length of the cube

From the diagram, the side length \( s \) of the cube is \( 12 \) millimeters.

Step3: Substitute the side length into the formula

Substitute \( s = 12 \) into the formula \( SA = 6s^2 \). First, calculate \( s^2 \): \( s^2 = 12^2 = 144 \) square millimeters. Then, multiply by 6: \( SA = 6\times144 = 864 \) square millimeters.

Answer:

864
