Answer 1

Answer:

235.404 cm³

Step-by-step explanation:

We have been asked to find the volume of the block .

The block consists of a cube and a hemisphere on top of it .

We will add both of the volumes and hence find the volume of the block .

Volume of the cube

Side of the cube is given as 6 cm .

Volume = side³

Volume of the given cube = ( 6 cm )³

⇒ 216 cm³ .

Volume of the hemisphere

Volume of hemisphere = 2/3 π r³

r = 4.2/2

⇒ r = 2.1 cm

⇒ 2/3 × 22/7 × ( 2.1 cm )³

⇒ 2/3 × 22/7 × 21³/10³ cm³

⇒ 2/3 × 22/7 × 21³/10³

⇒ 44/21 × 21³/1000

⇒ 44 × 21²/1000

⇒ 44 × 441/1000

⇒ 44 × 0.441

⇒ 19.404 cm³

Volume of the block

Volume will be 216 cm³ + 19.404 cm³

⇒ 235.404 cm³
