Answer
Question 1
Brief Explanations:
Mass is defined as the amount of matter in an object. The amount of space an object takes up is volume, the relationship between mass and volume is density, and how much an object can hold is capacity.
Answer:
The amount of matter in an object
Question 2
Explanation:
Step1: Recall volume formula
The volume formula for a rectangular - prism (since the given shape is not a cube but a rectangular - prism) is $V = l\times w\times h$.
Step2: Substitute values
Given $l = 5$ cm, $h = 10$ cm, $w = 15$ cm, then $V=5\times15\times10$.
Step3: Calculate
$V = 750$ cubic cm. But there seems to be a mistake in the options provided as the correct answer is not among them. If we assume it was a calculation error in the options and we recalculate $V=5\times10\times15 = 750$ cubic cm.
Answer:
There is no correct option among the given ones
Question 3
Explanation:
Step1: Recall density formula
The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass and $V$ is volume.
Step2: Calculate density of wood
For wood, $m = 15$ g and $V = 10$ $cm^{3}$, so $\rho_{wood}=\frac{15}{10}=1.5$ g/$cm^{3}$.
Step3: Calculate density of rock
For rock, $m = 20$ g and $V = 15$ $cm^{3}$, so $\rho_{rock}=\frac{20}{15}=\frac{4}{3}\approx1.33$ g/$cm^{3}$.
Step4: Compare densities
Since $1.5>1.33$, wood has a greater density.
Answer:
wood
