Given:
The dimensions of the given cuboid are 8 in, 6 in and 7 in.
To find:
The volume and the surface area of the given cuboid.
Solution:
The volume of cuboid is:

Where, l is length, b is breadth and h is height.


Therefore, the volume of the cuboid is 336 cubic inches.
The surface area of the cuboid is:

Where, l is length, b is breadth and h is height.




Therefore, the surface area of the cuboid is 292 square inches.
