Question

A block of has dimensions 4cm ,5cm and 25cm and a massof 1.280kg. find its density

Answer 1

As per relation we know a formula that,

d = Mass/Volume

Given :-

Mass = 1.280

Length = 4 cm = 4/100 = 0.04 m

Similarly,

Breadth = 0.05 m

Height = 0.25 m

Putting these values in formula,

d = 1280×100×100×100/4×5×25×1000

d = 2560 Kg m-³
