10-3Example 1
What is the surface area of the rectangular prism?
2. Find the area of the faces A and F.
A = l × w
A = 6 × 4 = 24
10-3Example 1
What is the surface area of the rectangular prism?
3. Find the area of the faces B and D.
A = l × w
A = 4 × 3 = 12
10-3Example 1
What is the surface area of the rectangular prism?
4. Find the area of the faces C and E.
A = l × w
A = 6 × 3 = 18
10-3Example 1
What is the surface area of the rectangular prism?
5. Find the sum of the areas of all the faces.
18 + 18 + 12 + 12 + 24 + 24 = 108
The surface area of the rectangular prism is 108 square units.
