Question

A metal block of length 4 cm;breadth 3cm and height 2.5cm weighs 500g.What is the mass of a block of length 5cm;breadth 4cm and height 3cm made of the same metal m

Answer 1

Blocks are of same metal so they have same densities.

So,  $p_{1} =p_{2}$

    $500g/30 ml = mass of block/60 ml$

    mass of block = 1 Kg
