Explanation:
The complete question is
How do you calculate the mass of a solid copper cuboid with a density of 9.86 g/cm^3. The dimensions of the cuboid are 10 cm by 3 cm by 5 cm
step 1
Find the volume of the cuboid
![V=(10)(3)(5)=150\ cm^3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/qammcyspzoj4tyqbp1o542mgwtz2vhf9dr.png)
step 2
Find the mass
we know that
To find out the mass multiply the density of the solid by its volume
so
![m=(9.86)(150)=1,479\ g](https://img.qammunity.org/2021/formulas/mathematics/middle-school/3izync1b1zk5qdgxrgq8mf7adkv0b3falt.png)
