What is the surface area of the cuboid?
To calculate the surface area of the rectangular prism, we will need to identify its three faces (each face appears twice):
1*3
1*8
3*8
The formula for the surface area of a rectangular prism is the sum of all the areas of the faces, that is:
We replace the data in the formula:
2*(1*3+1*8+3*8)=
2*(3+8+24) =
2*35 =
70
And this is the solution!
