Which is the volume of the solid?

The solid is made up of 2 cuboids. First cuboid has length as 4 unit cubes, height as 1 unit cubes and width as 2 unit cubes. Second cuboid has length as 1 unit cube, height as 3 unit cubes and width as 2 unit cubes.

A.
14 cubic units

B.
16 cubic units

C.
21 cubic units

D.
35 cubic units

To find the volume of the solid, we need to find the volumes of both cuboids and then add them together.

The volume of the first cuboid is:

Volume = Length x Width x Height
= 4 x 2 x 1
= 8

The volume of the second cuboid is:

Volume = Length x Width x Height
= 1 x 2 x 3
= 6

Therefore, the total volume of the solid is:

Total Volume = Volume of first cuboid + Volume of second cuboid
= 8 + 6
= 14 cubic units

So, the answer is A. 14 cubic units.
