Question

Find the surface area of the cube (above) using its net (below).

The figure presents a surface net of a cube. The net consists of 4 squares connected in a row. The second square from the left is also connected to a square above it, and a square below it. The length of one side of one square is labeled as 5 units.

Answer 1

150 units²

Explanation:

cube has 6 faces. All faces are congruent squares.

The area of a square is (side)².

Since there are 6 congruent squares, the total surface area of a cube is

6(side)²

SA = 6(5 units)²

SA = 6(25 units²)

SA = 150 units²
