The surface area of a rectangular prism is the sum of the areas of all six faces. To calculate surface area, we need to find the areas of each face and then add them all together.
Given dimensions:
Length = 4 inches
Width = 2.25 inches
Height = 8 inches
Calculate the areas of the six faces:
1. Front face = Length * Height = 4 * 8 = 32 sq. inches
2. Back face = Length * Height = 4 * 8 = 32 sq. inches
3. Top face = Length * Width = 4 * 2.25 = 9 sq. inches
4. Bottom face = Length * Width = 4 * 2.25 = 9 sq. inches
5. Left face = Width * Height = 2.25 * 8 = 18 sq. inches
6. Right face = Width * Height = 2.25 * 8 = 18 sq. inches
Now, add all the areas together:
32 + 32 + 9 + 9 + 18 + 18 = 118 sq. inches
Therefore, the surface area of the rectangular prism is 118 square inches.
