Question

find the surface area of the cube.

Explanation:

Step1: Find area of one face

A cube's face is a square. Area of one face: $\text{side}^2 = 6.5^2$
$6.5^2 = 42.25$ square inches

Step2: Multiply by 6 (total faces)

A cube has 6 identical faces. Total surface area: $6 \times 42.25$
$6 \times 42.25 = 253.5$

Answer:

253.5 square inches
