Question

The net of a solid figure is shown below:

Four squares are shown side by side in a row. The second square has a square above it and a square below it. All the squares have side length equal to 3 inches

Which calculation will give the total surface area of the solid figure?

please pick from the 4 below

3 × 6 × 6 square inches

6 × 3 × 3 × 3 square inches

3 × 6 × 6 × 6 square inches

6 × 3 × 3 square inches

Answer 1

D is the answer

Explanation:

Answer 2

Each square is 3 by 3, so the area is 3*3 = 9. We can leave it as 3*3 since that's what the answer choices show.

There are 6 of these squares, so the total area of this figure is 6*3*3
The total area of the net is the same as the total surface area when we fold along the lines to form a 3D cube

Final Answer: 6 x 3 x 3 square inches which is choice D
