#"Mass"=350*g#

By definition...#rho_"density"="mass"/"volume"#.

And CLEARLY to get the #"mass"# we take the product...#rho_"density"xx"volume"#... And so....

#"mass"=underbrace(2.76*g*cm^-3)_"density"xxunderbrace(3.50*cmxx5.00*cmxx7.25*cm)_"volume of granite block in cubic centimetres"=??*g#..

Is this product dimensionally consistent...?
