Answer:
37.5 square feet
Explanation:
Let me break it down into simple terms:
The question states, "cube with this net".
A cube has all 6 surfaces that are equal. The surface area is the area of each side added up.
In this case, since this net would form a cube, we can use the formula:
6·area of 1 square to get the surface area of the entire net.
We know that to find the area of a shape, it's simply length times width:
2.5x2.5
=6.25
Now, substitute that into the original equation (6·area of 1 square)
6(6.25)
=37.5
The surface area of this net is 37.5 square feet.
Hope this helps! :)
