3) 48g

Explanation:

d=0.8gcm^-3

v=60^3

mass=v×d

0.8×60g

=48g

\bigstar Given

A block of wood of density 0.8 g cm⁻³ has a volume of 60 cm³

\bigstar To Find

The mass of block

\bigstar Solution

We know that

\red{\sf \longrightarrow m=d \times v}

Here

  • m = mass
  • d = density
  • v = volume

According to the question

We are asked to find the mass of block

Therefore

We must find "m"

Given that

A block of wood of density 0.8 g cm⁻³ has a volume of 60 cm³

Hence

  • d = 0.8 g cm⁻³
  • v = 60 cm³

Substituting the values

We get

\orange{\sf \longrightarrow m=0.8 \ g \ cm^{-3} \times 60 \ cm^{3}}

On further simplification

We get

\pink{\sf \longrightarrow m=48 \ g}

Therefore

\star Mass of block = 48 g

Hence

\checkmark Option (3) is correct
