Answer 2

1st question's Answer

Volume of cuboid = 105 cm³

Volume = l x b x h

lbh = 105 cm³

7 cm x 3cm x y = 105w cm³

21 cm² x y = 105 cm³

y = 105 cm³ / 21 cm²

y = 5 cm

2nd question's ans.

Volume of cubois 1st = Volume of cuboid 2nd

lbh = LBH

7 x 4 x 2 cm³ = 2 x 1 x ( x ) cm²

x = 56 / 2 cm

x = 28 cm
