Find the total surface area of a cube whose each edge measures $5\text{cm}$.

Step-by-step solution

1. Area of one face of the cube = side${}^2=5^2=25{\text{cm}}^2$ because each face is a square.
2. A cube has 6 equal faces, so multiply the area of one face by 6: $6\times 25=150{\text{cm}}^2$.
3. Hence the total surface area of the cube is $150{\text{cm}}^2$.
