Question

what is the surface area of the shape? 2 in 2 in 2 in in.²

Explanation:

Step1: Calculate the area of one small square

The area of a square is \(A = s^2\), where \(s = 2\) in. So \(A_1=2\times2 = 4\) in.²

Step2: Count the number of small squares

By observing the shape, we can see that there are 5 small squares.

Step3: Calculate the total surface area

The total surface area \(A = 5\times A_1\). Substitute \(A_1 = 4\) in.², we get \(A=5\times4=20\) in.²

Answer:

20
