rock

Explanation:

Question 1

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.

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.

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ 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 $
ho_{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 $
ho_{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:

The amount of matter in an object
