The base and the height of a rectangle are represented by the expressions below.

PIT_PIT [208]

The length of the base is 27 and the length of the height is 17.

To find the answer, you need to add up each side twice and set it equal to 88.

x-6+x-6+x+4+x+4=88

That is equal to: 4x - 4 = 88

Add 4 to both sides: 4x = 92

Divide by 4: x = 23

Now plug 23 in for x:

Base: 23 + 4 = 27
Height: 23-6=17

A tennis ball is 2 inch in diameter. How many tennis ball will fill a room of 20ft by 16ft by 18ft if no space wasted?

krek1111 [17]

The number of tennis ball that will fill the room is <u>1,371 tennis balls.</u>

<em><u>Given</u></em>:

Diameter of ball (d) : 2 inch

Radius (r) = half of diameter = 1 inch

Dimension of room = 20ft by 16ft by 18ft

Number of balls that will fill the room = Volume of each ball/volume of the room

Volume of the ball = volume of a sphere = $\frac{4}{3} \pi r^{3}$

Where,

r = 1

let $\pi = 3.14$

<em>Substitute</em>:

$Volume = \frac{4}{3} \times 3.14 \times 1^{3} \\Volume = 4.2in^{3}$

Volume of the room = $20 \times 16 \times 18 \\$

$= 5,760$

Therefore:

number of tennis balls that will fill the room = $\frac{5,760}{4.2} = 1,371.4$

Therefore, the number of tennis ball that will fil the room will be <u>approximately 1,371.</u>
