Question

a net for a three - dimensional figure is shown on grid paper. each square of the grid paper represents 1 in². what is the surface area of the three - dimensional figure? area of rectangle a = l·w s.a. = in²

Explanation:

Step1: Count the number of squares

Count each square in the net. There are 34 squares.

Step2: Calculate surface - area

Since each square represents 1 in², the surface - area is the number of squares.
