Question

question 9 (multiple choice worth 4 points)
(06.04 mc)
what is the surface area of a square prism with sides that measure 8 units?
o 254 units²
o 300 units²
o 314 units²
o 384 units²

Explanation:

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

The surface area formula for a cube is \(SA = 6s^{2}\), where \(s\) is the side length of the cube.

Step2: Substitute the value of \(s\) into the formula

Given \(s = 8\) units. Substitute \(s = 8\) into \(SA=6s^{2}\), we get \(SA = 6\times8^{2}\).
First calculate \(8^{2}=64\). Then \(6\times64 = 384\).

Answer:

384 units²
