To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then add them up.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
where:
- l is the length of the prism
- w is the width of the prism
- h is the height of the prism
For example, if the length of the prism is 5 cm, the width is 3 cm, and the height is 4 cm, the surface area would be:
Surface Area = 2(5)(3) + 2(5)(4) + 2(3)(4) = 30 + 40 + 24 = 94 square cm
Therefore, the surface area of the rectangular prism is 94 square cm.
