Example 3

easy
Find the surface area of a cube with side length 66 cm.

Solution

  1. 1
    A cube has 6 identical square faces: SA=6s2SA = 6s^2.
  2. 2
    Substitute: SA=6(6)2=6(36)=216SA = 6(6)^2 = 6(36) = 216 cm².

Answer

SA=216 cm2SA = 216 \text{ cm}^2
A cube is the simplest rectangular prism where all edges are equal, making the surface area formula 6s26s^2.
