A wooden block is a rectangular prism. Its length is 8.0 cm, the length of one of the two perfect square sides is 2.0 cm, the mass of the wooden block on the digital balance reads 150 grams, What could be the density of the wooden block? Express your final answer in its proper significant digits and correct unit of measurement.
Answers
Answer:
im not sure but i think the answer is ρ=4.7 g/cm^3
Explanation:
Given:
length(l)=8.0 cm
width(w)=2.0 cm
height(h)=2.0 cm
mass(m)=150 g
density( ρ )= ?
Solution:
V=l×w×h
V=8.0 cm×2.0cm×2.0cm
V=32 cm^3
ρ=150 g/32cm^3
ρ=4.7 g/cm^3
Answer:
Wooden blocks have a density of 4.7 g/cm3 or less.
Explanation:
Explain about the density?
It is possible to measure a material's density by how closely it is packed. The mass per unit volume is how it is formally defined. Density Symbol (D or ) Density Formula m is the object's mass, and V is its volume, so that = m/V denotes the object's density. Water is frequently used as a reference.
Two different types of density exist: absolute density and relative density. The ratio of a substance's density to that of a standard substance is known as its relative density, sometimes referred to as specific gravity.
We can calculate what materials will float and sink when placed in a liquid using the concept of density, which is a crucial idea.
V= l× w × h
V = 8.0 2.0 2.0 cm
V=32 cm^3
ρ=150 g/32cm^3
ρ=4.7 g/cm^3
