Final answer:
The formula for the surface area of a box (rectangular solid) is 2lw + 2lh + 2wh.
Step-by-step explanation:
The formula for the surface area of a box (rectangular solid) is:
Surface Area = 2lw + 2lh + 2wh
Where:
- l is the length of the box
- w is the width of the box
- h is the height of the box
For example, if the length of the box is 4 cm, the width is 3 cm, and the height is 2 cm, the surface area would be:
Surface Area = 2(4)(3) + 2(4)(2) + 2(3)(2) = 52 cm²
