Question

a block of glass of mass 187.5g is 5.0 cm long. 2.0 thick and 7.5 cm high. calculate the density of the glass in kgm^3​

Answer 1

`2500 {kgm}^(3)`

Explanation:

Density =

`density = (mass)/(volume)`

Volume =lbh

Volume= 5x2x7.5

= 75cm^3

`density( {gcm}^(3) ) = (187.5)/(75) \\ = 2.5 {gcm}^(3) \\ to \: change \: from \: {gcm}^(3) to \: {kgm}^(3) \\ multiply \: by \: 1000 \\ 2.5 * 1000 \\ = 2500 {kgm}^(3)`
