Question 1- heather wanted to find the density of a solution with a mass of 2.234
grams and a volume of 2.131 milliliters. she uses the density formula,
density = mass/volume.
if both her mass and volume were accurately measured to the thousandths place what is an accurate value for the density measured in g/ml?

question 2- coleton measures the sides of a rectangular piece of plywood. one
side is 72.6 inches long, and the shorter side is 36 inches long. what is the area of
the piece of plywood, rounded appropriately using significant figures?

question 3- when would you want to use the median over the mean for
describing the measure of center for a data set?

For Question 1, you are given a  mass of 2.234 grams and a volume of 2.131 milliliters. You are asked to find the density of a solution. You will use the density formula to solve this. Density is equal to the mass of the substance over the volume displaced or D = M/V.

D = M/V
D = 2.234 grams/ 2.131 milliliters
D = 1.048 grams / milliliters or 1.048 g/mL

For Question 2, you are given a rectangular piece of plywood with one 
side 72.6 inches long, and the shorter side is 36 inches long. You are asked to find the area of the piece of plywood. The area of the rectangle is A = LW where A is the area, L is the length and W is the width.

A = LW
A = 72.6 inches x 36 inches
A = 2,610 in²
