Dear student
Let the edge of cube be l. When mass is on the cube of wood
200 g + l
3 d wood g = l
3 d
water g
⇒ l3 dwood = l3 dwater – 200 … (i)
When the mass is removed
l3 dwood = (l - 2 ) l2 dwater … (ii)
From (i) and (ii)
l3 dwater - 200 = (l- 2) l2 dwater
But d
water = 1
∴ l3 - 200 = l2 (l - 2)
⇒ l = 10 cm
Hence volume = 10³ = 1000 cm³
