64+64

128cm³

Answer 2

Answer :

• The Volume of the new solid is 128cm³.

Step-by-step explanation ::

To Find :-

• The volume of the new solid.

Solution :-

Given that,

• Two cubes each of side 4cm are joined together

Therefore, the volume of the cube of side 4cm is,

As we know that,

Volume of cube = a³ cubic units,

Where,

• a = side of cube

➟ Volume = a³

➟ Volume = (4)³

➟ Volume = 4 × 4 × 4

➟ Volume = 16 × 4

➟ Volume = 64cm³

According the question,

The Volume of the new solid is,

As given, the two cubes each of side 4 cm are joined together, therefore,

➟ Volume of cube + Volume of cube = New solid

➟ 64cm³ + 64cm³

➟ 128cm³

• Therefore, the volume of new solid is 128cm³.
