Question

A block of wood has dimensions 4cm,5cm and 25 cm and a mass of 1.280 kg. Find its density.​

Answer 1

Explanation:

density is equal to mass by volume. then volume=4•5•25(cm)^3=500cm^3.

1.280kg=1280g

density=1280/500=2.56g/cm^3.

Answer 2

given,

mass = 1.280kg = 1280gram

block of wood dimensions = 4cm, 5cm, 15cm

= volume = 4×5×25

= 500cm^3

= density = mass/volume

= dencity= 1280/500

= (2.56gram/cm^3) ans
