In determining the density of a rectangular metal bar, a student made the following measurements length 8 53 cm, width, 24 cm, height 10 cm, mass, 527064 g Calculate the
density of the metal to the correct number of significant figures​

Answers

Answer 1

Answer:

d = 2.57456 g/cm³

Explanation:

Given data:

Length of metal bar = 853cm

Width = 24 cm

Height = 10 cm

Mass = 527064 g

Density of metal = ?

Solution:

Volume of metal bar:

Volume = length × width × height

Volume = 853 cm × 24 cm × 10 cm

Volume = 204720 cm³

Density:

d = m/v

d = 527064 g / 204720 cm³

d = 2.57456 g/cm³
