Find the density of a block with a length of 8.0 cm, a width of 4.0 cm, a height 2.0 cm, and a mass of 32 g. Would this block
float or sink in water?

Explanation:

Density of a substance can be found by using the formula

From the question

mass = 32g

To find the density we must first find the volume of the block

From the question the block is a cuboid

Volume of cuboid = length × width × height

length = 8 cm

width = 4 cm

height = 2 cm

Volume of block = 8 × 4 × 2 = 64 cm³

Substitute the values into the above formula and solve for the density

That's....

We have the final answer as

Density = 0.5 g/cm³

The block will float because it's density is less than the density of water which is

1 g/cm³

Hope this helps you

d= 0.5 g/ cm³

The block will float in water.

Explanation:

The density of an object can be found using the following formula:

where is the mass and is the volume. We know the block has a mass of 32 grams. We don't know the volume, therefore we must calculate it.

Let's assume the block is a cube. The volume of a cube can be found using the following formula.

The length is 8 cm, the width is 4 cm and the height is 2 cm.

Now we know the volume and can substitute it into the formula, along with the mass.

Divide 32 grams by 64 cubic centimeters.

The density of the block is 0.5 grams per cubic centimeter. The density of water is 1.0 g/cm³. Any object with a density that is less than 1 will float in water. 0.5 is less than 1, so this object will float in water.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
