Answer:

The answer is 6.

Step-by-step explanation:

Given is that the total volume is 360 cubic inches

The height is fixed at 3 inches

So, total area will be = \frac{360}{3}=120 square inches.

Let's assume the minimum size in any dimension to be 3 inches.

Now we have to find possible combinations of numbers greater than 2 that will make 120. So, we have

3 x 40

4 x 30

5 x 24

6 x 20

8 x 15

10 x 12

These have the same answer in reverse order as well. So we will consider these.

Therefore, there are 6 different paving stones with different base.

1200 centimeters

Step-by-step explanation:

if you have 100 centimeters in 1 meter and there are 12 meters you can just multiply the number of centimeters by 12 or whatever number is needed in this case 12 so when you multiply 12 x 100 you get 1200

A gas has weight of 5 pounds and a volume of 100 cubic feet. what's the specific volume of this gas
Leya [2.2K]

In thermodynamics, specific volume is considered to be an intrinsic property of matter. What we meant by intrinsic property is that, the value of this property does not change no matter the size of the sample. This is opposite to weight or volume which changes depending on the size of the sample.

By mathematical definition, specific volume is the ratio of the substance’s volume to its mass. Or in other words, this is the reciprocal of density.

The formula for density is:

density = mass / volume

Since specific volume is reciprocal so:

Specific volume = 1 / density = volume / mass

 

Calculating:

Specific volume = 100 ft^3 / 5 pounds

Specific volume = 20 ft^3 / pound

 

Or when asked in units of m^3 / kg, we convert:

Specific volume = (20 ft^3 / pound) (2.2 pound / kg) (1 m^3 / 35.3147 ft^3)

Specific volume = 1.246 m^3 / kg
