Answer
(a) The object's density is
(b) The other object's volume equals
.
Explanation
## Step1: For part (a), calculate the density of the object given its mass and volume. The formula to calculate density, let's denote it as
, is
, where
represents mass and
indicates volume. The provided values in the question are: mass
and volume
. Substituting these values into the formula would help us work out the density.## Step2: For part (b), we need to ascertain the volume of the object using given values of its mass and density. This can be accomplished by manipulating the density formula to isolate volume---
. We come up with a new equation -
where
is mass and
pertains to density. The parameters available to us from the question are: mass
and density
. Inserting these values into the new volume equation will help in computing the needed value of volume.# Calculations:###
