Question

A rectangular concrete slab is 0.80m long, 0.60m wide and 0.04m thick. The mass of concrete slab is 180kg. Calculate its density in kg/m3

Answer 1

density,= mass /volume

so divide mass by volume

Answer 2

Answer:1.067 (approximately)

Explanation:

Density=mass/volume

here volume is not directly given but we can calculate it

as,

Volume=length x breadth x hieght

therefore,

Volume=0.80m x 0.60m x 0.04m

=0.0192m^3

given mass=180kg

so, density = 0.0192m^3 / 180kg

=1.067 (approximately)

NB:- kindly recheck the calculations
