A crate with no lid is shaped like a cube with sides that are 0.8 m long. What is the surface area of the crate?

2.6 m²

3.5 m²

2.9 m²

3.2 m²

1 answer

The surface area of a cube can be found by calculating the area of each side and then summing them up.

Since all sides of the crate are 0.8 m long, each side has an area of (0.8 m)(0.8 m) = 0.64 m².

Since a cube has 6 sides, the total surface area of the crate is 6 * 0.64 m² = 3.84 m².
