Answer:

1165.83 kg

Explanation:

The total mass is the product of volume of one brick, the number of bricks, and the density. For this problem, it is convenient to use dimensions in meters.

[tex] (0.051\,m)(0.102\,m)(0.203\,m)(600)\dfrac{1840\,kg}{m^3}=(0.6336036\,m^3)\dfrac{1840\,kg}{m^3}\\\\=1165.83\,kg[/tex]

Answer:

1165.83 kg

Step-by-step explanation:

600×(5.1 cm × 10.2 cm × 20.3 cm) = 633,603.6 cm3

633,603.6 cm3 × 1 m3/10^6 cm3 × 1840 kg/m3= 1165.83
