Question

question 5 of 10 what is the surface area of the cube below? 7 7 7 a. 147 units² b. 254 units² c. 508 units² d. 294 units²

Explanation:

Step1: Recall surface - area formula

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

Step2: Identify side - length

The side - length of the given cube $a = 7$.

Step3: Calculate surface area

Substitute $a = 7$ into the formula: $S=6\times7^{2}=6\times49 = 294$.

Answer:

D. 294 units²
