Question

incorrect the value in your answer is incorrect. find the surface area of this cube. be sure to include the correct unit in your answer. cube diagram with side length 9 yd (labeled 9 yd on each edge)

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 \( 9 \) yards.

Step3: Substitute the side length into the formula.

Substitute \( s = 9 \) yd into the formula \( SA = 6s^2 \). First, calculate \( s^2 \): \( 9^2 = 81 \) square yards. Then multiply by 6: \( SA = 6\times81 = 486 \) square yards.

Answer:

\( 486 \) square yards (or \( 486\ \text{yd}^2 \))
