Question

a wood block had dimensions 10 inch
6 inch x 2 inch and
weighs 3 lb. Find
ito density in
a)gcm3 b) kg m
-3
m​

Answer 1

Step-by-step explanation:

initially converting all measures in cm

10 inch = 25.4 cm

6 inch = 15.24 cm

2 inch = 5.08 cm .

volume = 25.4 × 15.24 × 5.08 = 1966.45 cm³

Mass = 3 pounds = 1360.7 gm

Therefore Density = mass / volume

density = 1360.7 / 1966.45 g/cm³

= 0.6919 g/cm³

now in kg / m³

density = 1.36 kg /0.00196645 m³

= 691.95758 kg/m³
