The smaller edges at the base of the rectangular parallelepiped made of steel are 6 cm and the distance between them is 8 cm. The height of the parallelepiped is 7 cm. Find the mass of the parallelepiped if the density of steel is 7.8 g / cm3

1. Determine the mass of a rectangular parallelepiped made of steel, according to the formula:

m = W x H x L / 1,000 x p,

where

m is the mass of a rectangular parallelepiped;

W is the width of the rectangular parallelepiped;

H is the height of the rectangular parallelepiped;

L is the length of the rectangular parallelepiped;

p is the density of the rectangular parallelepiped material.

m = 6 cm x 8 cm x 7 cm / 1,000 x 7.8 g / cm3 = 336 cm / 1,000 x 7.8 g / cm3 = 0.336 x 7.8 g / cm3 = 2.62 g.

The mass of a rectangular parallelepiped is 2.62 g.
