base = 12
height = 1.5
what is the surface area of the box?
To find the surface area of the box, we need to find the area of each of the 6 sides and then add them together.
The 6 sides of the box will include:
1. The base with dimensions 12 x 1.5
2. The top with dimensions 12 x 1.5
3. Two sides with dimensions 1.5 x 1.5
4. Two sides with dimensions 12 x 1.5
Calculate the area of each side:
1. Base and top: 12 * 1.5 = 18 square units each
2. Two sides with dimensions 1.5 x 1.5: 1.5 * 1.5 = 2.25 square units each
3. Two sides with dimensions 12 x 1.5: 12 * 1.5 = 18 square units each
Add all the areas together:
18 + 18 + 2.25 + 2.25 + 18 + 18 = 76.5
Therefore, the surface area of the box is 76.5 square units.
