Question

whats the surface area of a cube with a side length of 5 inches? a. 150 b. 25 c. 125 d. 175

Explanation:

Step1: Recall surface - area formula

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

Step2: Substitute the side - length value

Given $s = 5$ inches, substitute $s$ into the formula: $S=6\times5^{2}$.

Step3: Calculate the result

First, calculate $5^{2}=25$. Then, $6\times25 = 150$ square inches.

Answer:

A. 150
