Question

A rectangular block of fin is 0.5 m long and 0.0lm thick Find the width of the block if its mass and density are 0.45 kg and 9000kgm-³ respectively ​

Answer 1

Explanation:

This is going to give you a preposterous answer. The width is into the millions.

density = 9000 kg / m^3

mass = 0.45 kg

V = density / mass

V = 9000 / 0.45 = 20000 m^3

V = L *w * h

L = 0.5 m

h = 0.01 m

w = ?

20000 = 0.5 * 0.01 * w

20000 / (0.5 * 0.01) = w

w = 4000000 m

If something has been miscopied let me know. The numbers are correctly handled I think
