Question

please help me with this​

Answer 1

Given,

1. Initial Volume of cylinder (v) = 50 mL

After stone was dipped,

Final Volume of cylinder (V) = 70 mL

∴ V-v = Volume of Stone

= (70-50) mL

= 20 mL

or,

= 20 cm³ [because 1 mL is equal to 1 cm³]

2. If the metallic ball displaces 10 mL of water then it's own volume must be 10 mL or, 10 cm³ only.

I hope this helps.
