1. The density of a material in the shape of acube is determined by me

1.	1. The density of a material in the shape of acube is determined by measuring three sidesof the cube and its mass. If the relative errorsin measuring the mass and length arerespectively 1.5% and 1%, the maximumerror in determining the density is(a) 2.5%(c) 4.5%(b) 3.5%(d) 6%
Answer» Density = Mass / Volume 1Δd/d = 1ΔM/M + 3ΔL/L = 1.5 + 3×1 = 4.5% tHankeWw

Answer»

Density = Mass / Volume

1Δd/d = 1ΔM/M + 3ΔL/L

= 1.5 + 3×1

= 4.5%
