Answer:

Density is usually expressed as grams per cubic centimeter.

Volume = 55 * 25 * 20 = 27,500 cc

Density = Mass / Volume = 4,000 grams / 27,500 cc

= 0.1454545455 grams/cc

which is an extremely low density

\frac{35}{4} feet below the surface

adding the 2 quantities

3 \frac{1}{2} + 5 \frac{1}{4}

= (3 + 5 ) + (\frac{1}{2} + \frac{1}{4})

= 8 + (\frac{2}{4} + \frac{1}{4})

= 8 + \frac{3}{4} = 8 \frac{3}{4} = \frac{35}{4}

Answer:

The length of the slide is 10 feet.

Step-by-step explanation:

To find the length of the slide you have to use the formula:

a^2 + b^2 = c^2 (^2 means squared)

In this case:

a= 6 and b=8 c= unknown

6 squared (6 times 6) is 36

8 squared (8 times 8) is 64

Add these two numbers to get:

36+64=100

6^2+8^2=100

However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.

What number times itself equals 100? 10.

The length of the slide in 10 feet.
