!PLEASE HELP ME!

A block of material measures 0.20m by 150. cm by 6.0mm and has a mass of 2.6 kg. What is the density in g/
{cm}^{3}cm3

Answer 1

1.4 g/cm³

Step-by-step explanation:

1. Calculate the volume of the block

V = lwh

Data:

l = 150 cm

w = 0.20 m

h = 6.0 mm

(a) Convert all units to a common base

w = 0.20 m × (100 cm/1 m)

w = 20 cm

h = 6.0 mm × (1 cm/10 mm)

h = 0.6 cm

Calculation:

V = lwh

V = 150 × 20 × 0.60

V = 1800 cm³

2. Calculate the density

Density = mass/volume

Data:

m = 2.5 kg

Calculation:

m = 2.5 kg Convert to grams

m = 2.5 kg × (1000 g/1 kg)

m = 2500 g

Density = 2500 g/1800 cm³

Density = 1.4 g/cm³
