What metric unit of measurement would best be used to measure the mass of a candy bar?
Gram.
What is the mass of a gold bar 30 cm x 10 cm x 10 cm if the density of gold is 19.3 g per cubic centimeter?
To calculate the mass of the gold bar, you first need to find its volume. The volume of the gold bar is 30 cm x 10 cm x 10 cm = 3000 cubic cm. Next, you multiply the volume by the density of gold (19.3 g/cm³) to find the mass. Therefore, the mass of the gold bar would be 3000 cm³ x 19.3 g/cm³ = 57,900 grams.
How is a stacked bar different from other bar graph?
In a normal bar graph, each bar represents one value. In a stacked bar graph, each bar has a number of values, stacked on top of each other. So a bar can show how a total is broken down. So each bar could represent a year, with the amounts for each month indicated by different parts of that one bar.
