1 An ice cube has the following dimensions. 5.5 cm
8.4 cm
8.0 cm
Its mass is 340 g. Calculate:
a its volume
bits density.

a)V=lbh

=5.5cm ×8.4cm×8.0cm

=369.6cm^3

b)Density=Mass/Volume

=340g/369.6cm^3

=0.92g/cm^3.

Explanation:

Looking at your question, I thing if the shape of an object you're measuring is square, the length of all its side must be the same. In my opinion, I think the values of the lbh in the question are of a rectangle, which makes more sense.
