To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the length of a side of the cube.
Given that the side length of the cube is \( 1.5 \) meters:
-
First, calculate \( s^2 \): \[ s^2 = (1.5)^2 = 2.25 \text{ square meters} \]
-
Now calculate the surface area: \[ \text{Surface Area} = 6 \times 2.25 = 13.5 \text{ square meters} \]
Thus, the surface area of the cube is 13.5 square meters.
