Answer:
4551 grams
Step-by-step explanation:
You want the mass in grams of a block of ice with dimensions 3.5 in by 7.5 in by 11.5 in and density 0.92 g/cm³.
The mass is the product of volume and density.
m = ρV
m = (0.92 g/cm³) × (3.5 in)(7.5 in)(11.5 in) × (2.54 cm/in)³
m ≈ 4551 g
The mass is about 4551 grams.

Additional comment
The density being in metric units means we need to do units conversion. We do that by multiplying by a conversion factor that has the units we want in the numerator (cm) and the units we don't want in the denominator (in).
Both units are cubed, so we have to cube the conversion factor. The numbers in the conversion factor are equals:
2.54 cm = 1 in.
