Question

you can use the formula $a = 6s^2$ to find the surface area of a cube with edge length $s$. a cube has edges that are 10 in. long. what is the surface area of the cube? show your work.

Explanation:

Step1: Identify the formula and given value

The formula for the surface area of a cube is \( A = 6s^2 \), and the edge length \( s = 10 \) in.

Step2: Substitute the value of s into the formula

Substitute \( s = 10 \) into \( A = 6s^2 \). First, calculate \( s^2 \): \( 10^2 = 100 \). Then multiply by 6: \( A = 6\times100 = 600 \).

Answer:

The surface area of the cube is 600 square inches.
