Four students made statements about a tenis ball they were using in a lab.
irma: i used a ruler to measure the radius and then an equation to calculate the volume as 104cm³.
julia: i used a scale to measure the mass as 0.6kg.
grace: i used a scale to measure the weight to be 0.28 lb.
masha: i used a bucket of water and a ruler to measure the volume as 98cm³.
which student made a mistake in their statement.
i wanna say julia cause you don't use a scale to measure mass, but just wanna be right.
