Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find its area if a cube has a side length of 8 units. |
|
2 |
Step |
Given that the side length (s) is |
\$8\$ units |
3 |
Formula: |
The formula for the surface area of a cube with a side length "s" is: |
Area = \$6 \times(s)^2\$ |
4 |
Formula: |
Substitute the values into the formula |
\$6 \times(8)^2\$ \$6 \times 64\$ = \$384\$ |
5 |
Step |
So, the area of the cube is |
\$384\$ sq.units |
