Surface Areas and Volumes
- Surface areas of cuboid:
Lateral surface area of the cuboid = 2h (l + b)
Total surface area of the cuboid = 2 (lb + bh + hl)
Note: Length of the diagonal of a cuboid =
Find the edge of a cube whose surface area is 294 m2.
Let the edge of the given cube be a.
∴ Surface area of the cube = 6a2
Given, 6a2 = 294
