Answer:

Find the volume, then multiply it by the density.

Explanation:

1) Convert each length to #"cm"# (because #"1 cm"^3 = "1 mL"#)

2)Multiply the converted lengths by each other to get the volume

#"25 cm" xx "50 cm" xx "70 cm" = "87500 cm"^3 = "87500 mL"#

3) Multiply the volume by the given density

#"87500 mL" xx "0.8 g/mL" = "6000 g " -># one significant figure
